This Dark Matter Hunter Is Built With Quantum Computer Parts

Dark matter is everywhere. It’s not just
out in space. We’re flowing through an entire wind of dark matter.
As you sleep, they’re under your bed, they’re in your closet. They’re passing through
you right now. The decades long quest to understand what dark matter is, a mysterious substance
that makes up most of the mass in the universe, and force it to reveal itself is taking a
new experimental turn. Scientists have built this advanced instrument with parts from a
quantum computer that’s sensitive enough to listen for the signal of a dark matter
particle. It’s a scanning experiment. Like an AM radio we have a knob that we’re very,
very slowly tuning. And if they hit just the right frequency where dark matter might be
hiding. It’s going to be a fairly narrow tone, so just a hmmmmm. When you get to particle
physics, it turns out everything is waves. So even our particles are waves. Sound
is a wave. You can imagine each particle as a particular note. They have very specific
energies whereas they sit around there. And energies in physics correspond to frequency. This is like setting a musical
scale. You’re listening for what would sound like a tone, amidst a sea of white noise.
There’s numerous astrophysical measurements that look at things in the universe. There’s
things out there that are interacting gravitationally that aren’t stars, they don’t seem to be
dust, they’re not planets as far as we can tell. You find that this extra stuff out
there isn’t even made of atoms. This is very peculiar because you’re made of atoms, I’m
made of atoms, almost everything we can study is made out of atoms. And this means there’s
something new and different out there, some new different particle, and we call it, dark
matter. The theorist sees the astrophysical observations and says a-ha, there’s something
new out there. And they’ve got a set of things that could exist, but don’t necessarily do exist.
The experimentalists job is to basically go through these…one at a time. On the list
are some dark matter particles with names as weird and curious as the physics behind
them. People have heard of WIMPS. There’s also MACHOS, which is kind of the exact opposite
of a WIMP. Those are massive astronomical compact halo objects. Think black holes. There’s
WIMPzillas. There’s WISPS. Hidden sector photons. There’s stealth dark matter. And
the star of this episode that’s getting this big experimental push is called – the
axion. This theoretical particle was named after laundry detergent in the 1970s because
it could clean up two big problems in physics: dark matter and the strong CP problem. This
is another perplexing mystery that involves a surprising balance between two of the fundamental
forces of nature: the strong force and the weak force. One way to think about it simply
is. If you see a pencil that’s kind of just sitting there on his head and not falling
over. That’s strange. It should fall over unless something else is holding there. The
best idea for that is something called Pecci and Quinn Symmetry. Which basically cleans
this problem up and explains oh yes there’s this natural cancellation, and the only side
effect is this extra particle called the axion. It’s produced in large amounts in the early
universe and doesn’t interact very much so it’s still there, and so just as a consequence
of fixing this nuclear physics problem, you have stuff out there, gravitating, not interacting,
and it fits the bill for dark matter just perfectly. It’s too good of a coincidence
to not pursue, to go out and try and find the axion. Okay, so how do physicists set out to find
this hypothetical particle that may or may not exist? First, follow the theory. It’s
almost certainly very light and when I say very light I mean much lighter than an electron.
Being light actually makes it much more wavelike than particle like. It would act a lot like
a radio-wave that carries a little bit of mass. With the right conditions, you can convert
energy between axions and real radio waves. Basically you just need a strong magnetic
field that can do this conversion process. Then, build an instrument that’s specially
designed to do this called a haloscope. It’s basically a telescope, but looking for the
dark matter halo. The whole experiment sits in a large magnet, around 8 Tesla, and that
promotes the conversion of axion dark matter into detectable radio waves. And we do this
inside a microwave cavity, which is like a big soda can made out of copper. The cavity
itself is actually tuned by two tuning rods, those are positioned here and here. They’re
connected all the way to the top by a couple of gear boxes. And the idea is that within
this cavity, you move the tuning rods slowly, like you kind of tune an AM radio, and you
tune the resonant frequency of the cavity. This little doo-hickey right here is the actual
antenna. So, that’s what we put into the cavity to pull all the power out. From there,
all the power gets sucked into something that’s stored in here, which is called our quantum
amplifier package. The whole thing is kept cool by this right here which is our dilution
refrigerator. Because axion interactions are so weak. You
need almost no background, and there’s plenty of background just from things just having
a temperature, they just radiate. So you need technology to make yourself very very cold.
And that’s where we’ve tied in a bit with quantum computing, because quantum computing
involves making measurements at the bounds of quantum mechanics. There’s been a lot
of development of radio scale amplifiers and ultra sensitive electronics that work at these
ultracold temperatures. So while they’re trying to read out their qubits, the same
sort of devices can be used to detect extremely small sources of power that might be coming
from dark matter. The difficulty is you want the cavity to be at a particular frequency
that corresponds to where you want to look for the axion, that frequency has a lot of
wiggle room according to theorists. We start around 500 megahertz and working our way up
to 10 gigahertz. We’ll look in one region, one frequency range. We’ll not see any power
out. And then we move to the next range and we have to be able to scan that very quickly.
Most of the experiment is in keeping the experiment running. It has many moving parts, many complicated
systems, they all have to be maintained, when they break you have to fix them.
Which is exactly what happened when we came to visit. So this is a persnickety issue with
doing stuff at cryogenics. We were just putting signals through the system. As we cool down,
those power levels dropped, which doesn’t make any sense. We’re trying to diagnose
what we think is a fault in the line. It’s a very critical cable that’s coming out
of our experiment which would measure power from the axion if the axion were to interact
in our magnetic field. There are experiments that have many thousands of cables, and you
don’t want to go through and examine them all by eye, right. We would do a measurement.
We would take the next cable off, do a measurement. And at that point, we actually got to where
the error was. “I think he just disconnected it at the top.” “Oh at the top.” “He
just did.” “That’s interesting, because I think that’s where the break is, just
looking at this.” “Oh hold it, woo!” Due to strain on the cable, part of the pin
actually just pulled back. Things strain and contract when things get cold. And so that
caused this little gap to appear. We would not have been able to take good data with
that. We’ve recently crossed the threshold where we are now sensitive enough to the types
of interactions that theorists predict for axions. Kind of the exciting thing is any
day, you could just hit it and it’s there and it’ll be obvious and clear. My dream
is that I get a call or I’m looking at the data. Like that little peek there. Let’s zoom
in on that, let’s take a little bit more data on that. That peak is staying there.
Let’s move that magnet down. But so far… By and large, it has been white noise. The
axion parameter space um, is quite wide and unexplored. So with this experiment, we’re
going to move eventually into a multi-cavity system, and that’s to get to higher frequencies.
If we were to explore the entire possible range, if there is no axion out there, then
we need some new ideas. A no result actually goes and pulls the floor out of other areas
of physics that are very interesting. Dark matter is a difficult problem. You have to
be motivated by this mystery. To push the envelope, to actually discover things, you’re
going to have to do that cutting edge work. You have to be able to fail. Even if it’s
a complete failure of the experiment, you don’t find anything, that’s not actually a
failure. You’re exploring the boundaries.

  1. Why everyone refuse to think that maybe dark mater may be conected with eter.. why are we so ignorant… and why every new idea is rejected so bad….

  2. over-sensationalized title.

    wimps and axions have been dark-matter candidate particles for decades among all the other candidates. different groups have different favourite dark-matter candidates because no one can work on everything.

  3. I wonder if instead of electromagnetic energy flowing through the tubes, what if they used matter that may interact with dark matter and axion. That might work.

  4. The world: f***! the economy is crashing due to the virus crisis! We need to act fast!
    Physicists: let's find the imaginary pink unicorn

  5. One of these days a theoretical physicist will be open-minded enough to take some DMT and afterwards realise what dark matter, dark energy, higher dimensions, etc are.

    Can you just imagine where we'd be if the likes of Einstein or Hawking had a truly mystical experience together with their incredibly insightful intellect…

  6. Professional magicians are capable to build extremely sophisticated setups to persuade you that the impossible is possible. That's exactly what you see here.
    These people can't even understand or give usable models about what matter, light or "physical attraction" really are. They are piling theories on theories on theories.

  7. bull dookies. dark matter is a complete fabrication to "splain" what known physics cannot – you might as well call it Little Green Men

  8. “How do you cast spells?”
    Oh, that is simple. Everything around you is vibration waves. I simply pull the strings.

  9. Why does this some how sound like it's produced for children?……so stupidly simplified. It's almost so much it makes the physics sound like bullshit.

  10. this hypothetical nonsense is really just preying on the stupidity of most people.
    Billions of tax dollars wasted in search for made up nonsense , necessary to further complicate equations full of undefined variables.

  11. Hi Seekers, thanks for watching! For more on the hunt for dark matter, check out this How Close Are We?:

  12. Trillions of dollars spent looking for a particle that does not exist , Plasma Science and Electromagnetism are hammering the final nails into the Gravity centric Dark Matter sham… of luck on your new jobs !

  13. I'm telling you, dark matter is nothing more than gravity. Gravity is made of particles. Massless, invisible particles filling the universe. These particles are ATTRACTED to mass or matter. The bigger the mass the more the attraction. Gravity is these particles pushing toward and on a object from all sides unless there is another object overriding the first. It works similar to fluid dynamics and is referred to as a " hyperfluid". The reason dark matter is so hard to find is because its staring the scientists in the face. The latest experiment with LIGO and gravity wave detection prove this theory.

    But it's only my theory.
    Good luck ya'll!!

  14. Crazy thought; the background noise from the Big Bang? That’s actually emitted by all the dark matter in the universe?

  15. Hundreds of billions of tax payers dollars 2 find dark matter. Could've solved world hunger.. Yeahh, go scientist. Psst!

  16. Juat a reminder, folx, when they say dark its just a word to describe in a cool way that they simply dont know enough about it and cant see it. I think scientists need to be careful because alot of folx are mystfying terms not realizing its a fancy way of saying I dont know.

  17. it's a f'''ing theory, yet these theoretical scientists talks as if it's a proven fact. Fact is they're struggeling to stay on a boat floating on a sea that doesn't exist.
    Plasma cosmology is coming to take their jobs!

  18. Lol this video is so misleading.

    Dark matter is not “going through you”.

    We literally do not know what dark matter is. It could be massive objects that we can’t see. It could be blackholes that are undetectable to us. Or something else. We just *don’t know*.

    Or it could be a particle. In which case it could be going through, but again, we *don’t know*.

  19. Just forget about standard model of cosmology and switch to Electric/Plasma Universe model which is experimentally proven first by electrical engineer Eric Dollard with Tesla Coils electrically creating little fractal stars and galaxies from metal vapor and gases inside the partial vacuum of burned-out light bulb and then by Safire Project with their Electric Sun experiment. Google "Eric Dollard – How to create Stars, Nebula and Galaxy with Tesla Coils" and youtube search "The Safire Sun".

  20. maybe dark matter is only visible in higher dimension and it's effect is only active in 3rd all these gears and other stuff built within 3rd dimension realm is just wasting time & money. if it's sth only in higher dimension,it's much better suited to explain why whole universe is exist the way it is and it's structure,etc… and even how big bang was made possible.

  21. "a substance"…???? how do you know this dark matter exists if you cannot observe this substance….. on any level?

  22. So I guess these people who balance stones are finding the axions that happen to be around at a given time.

  23. So basically what you're saying is that frequencies have healing powers that I can use to cleanse toxins from my chakras. Science is just catching up to what we've known for millennia. Wake up!

  24. Dont tuch the device when you talk about the parts.

    It is like when people pointing on the screen with a pen.

  25. Dark matter is a fairytale… countless billions of taxpayers money has been wasted on The search for a theoretical particle.

  26. watching 'video' of this shit for the most part pisses me off, mostly because they're not following non-contamination protocols. the asian dude explaining things is wearing a hair net[lmao] and surgical gloves….yet his mouth is spewing millions of bacteria and droplets of water on the equipment… FF'S!

  27. my personal belief, is they will never find "dark matter" of the sort theyre looking for. My best educated guess, is they got the math wrong at the start 'period' "." There are thousands of astrophysicists looking for stuff 'out there' that was only thought of because the earlier math a hundred years ago couldnt account for. Even using todays math, they still cant figure it out,. This of course does not include Quantum physics…which until they can prove beyond a doubt "works",…[reliably] all looks like wishfull thinking. and using their own terminology, 'does and doesnt exist at the same time'. lol

  28. I don't trust The Edge of Physics experiments much now-a-days as they involve too much new tech with a lot of room for error. Why should dark matter be abundant everywhere? Perhaps it's displaced into interstella and intergalactic voids but still gravitationally bound to the star or galaxy… Could a material have gravity itself (intrinsic pull) but be repelled by strong gravity wells? Perhaps the concentration of light in stella systems and galaxies repells dark matter, thus forming 'halos'… Of course, this is just conjecture that fits the observed gravitational anomolies. Axions have more technical merit so I better experiments evolve.

  29. Why are some particles not interacting with matter?
    Do they stay in wave form?
    And if they don't interact, what makes them interact once in a long while?

  30. Dark matter & Dark Energy is simply the Cosmos' collective unconscious. The observer is no longer separate from the observational experiment. Know thy self

  31. What degree, in what faculty does the author of this has? Asking for a friend of a friend, which if you look closely could be me.

  32. > As you sleep, they're under your bed, they're in your closet. They're passing through you right now.

    OH. MY. GOD!

  33. There is NO dark matter ! Please check out suspicious for facts! Hint , PLASMA ELECTRIC UNIVERSE👍🇦🇺🙏

  34. Yeah because if you do an experiment and you completely fail you know not to do that experiment anymore so that's just one off the list and that's the closer you are to finding the right experiment. You know how a fish doesn't know it's in water? I believe we are in some type of substance also that we don't realize we are in and that would be dark matter but from a different type of entity looking at us knows exactly what it is that we are in and can see it all around us just like we can see water around the fish

  35. We are looking for something we don't anything about. It is like looking for a ghost, it is probably not real but lets prove it is! This is probably the hardest science but if it's proven can make great super weapons to wage robot wars! Seriously though, insane work.

  36. What we do know about dark matter. It is stable, long lasting and measurable. It has gravitational properties of dense matter. It is not attracted to, nor interacts with other dark matter at a Galaxy scale (two galaxies can pass through each other without disturbing the dark matter to any significant or permanent degree). KG for KG Dark Matter produces a force of 80x normal matter. The almost knowns. It almost certainly interacts with magnetic fields at a Galactic level. It's density and effect is linear across a Galaxy (It is as strong at the edges of a Galaxy as in the Central Bulge). Together these knowns and almost certainly knowns would strongly indicate Dark Matter is a strong magnetic force "permanently" bound to normal magnetic field matter (stars, Blackholes etc). Once bound to or formed by normal matter it cannot unbind or transfer it binding to any other passing matter. It is much like a permanent electro magnetic field. This sounds like WIMPS (weakly interacting magnetic particles). So there are either far more WIMPS than we can imagine or they are SIMPS (strongly interacting magnetic particles). Both WIMPS and SIMPS are produced by Magnatars and Neutron Stars. Magnatar stellar eruptions literally send Mega Gauss 1m Trillion Gauss across the Galaxy. Theses particles are strong interacting electro magnetic particles. Our Milky Way Galaxy has around 50 of these stars active at any one time producing 50 million trillion Gauss per 1 eruption for each of the 50 Magnatars. These particles must end up somewhere. The eruptions can strip atmospheres from planets at 20,000ly and ionise molecular gas clouds at 50,000ly. The majority of the particles end up in the Galaxy Halo. So we now have a source, a transport and an effect mechanism that may fully explain Dark Matter.

  37. Whats more scarier is we are chasing something that doesnt even exist at the first place. Its Like proving God exist but he doesnt want to know that he actually exist he hides himself in the shadow. Invisible.

  38. Man so crazy awesome like how…. Okay like it needs a super hell out of mind to get all these stuff in to our mind

  39. I don't understand some things. People are trying to find the cure for Covid using molecular simulators to find the vaccine. We have 7 super computers and all ''BIG'' companies brag with quantuum computers ''that can do in 2 hours what a supercomputer does in 10.000 years'' if i remember correctly. Yet, i don't see this ''SUPER TECHNOLOGY'' used for finding the cure. Why is that? Why are normal people computers used for this and not these ''amazing'' super computers? What is the purpouse of this so called quantum computing supremacy? Is it only for show i suppose, or…is it even real?!
