The 2nd Quantum Revolution -- Nobel Prize in Physics 2022

Check out the math & physics courses that I mentioned (many of which are free!) and support this channel by going to brilliant.org/Sabine/ where you can create your Brilliant account. The first 200 will get 20% off the annual premium subscription.
Today I speculate about the Nobel Prize in Physics, and explain why I think it's overdue to go to Aspect, Clauser, and Zeilinger. The probably coolest thing to have come out of their work is quantum teleportation.
At 10 mins 30 seconds I refer to a "list". I didn't mean to say that there literally is such a list! I just meant that they have been discussed as candidates for a long time and almost certainly have been nominated repeatedly.

When that same measurement is used, the "hash" reveals the information she mixed in the first particle. To understand how that works is not really what she explained, just that it can work. It's still very confusing, but the principle is that the information itself is never sent, so it can't be intercepted in any way. The information about her measurement could be, but it's no help to the interceptor because they have no access to the second particle. In this sense, it's a foolproof encryption. There is no communication between the particles.

[@WWLinkMasterX]

The metaphor I like to use is a pair of magic treasure chests: Putting an object in one chest and closing the lid teleports it into the other, regardless of how far apart they are. However, upon closing the lid, this generates a magic key that must be used to open the other chest. The key must be transported classically, below the speed of light. You can try to force open the 'receiver' chest without the key, but that destroys whatever is inside. So it's not not really good for transportation, but security.

[@thurston2235]

If this is an accurate analogy, it really helps me understand it. What I don’t get is why quantum teleport something at all when you still have to send other information classically? Is it only useful for encryption and that’s it?

[@michaelpettersson4919]

Of some reason this reminds me of how some shopkeepers in Baldur's Gate shared their inventory. So you could sell an item to one merchant and then buy it back from another... 😉

[@WWLinkMasterX]

@@thurston2235 Well, presumably it's physically *unhackable* encryption, which has it's value. And though the cost of the quantum computers needed to do it would exceed most practical expenses, I can see it being worth it for governments handling top secret data. Say, nuclear weapons codes. The other potential benefit depends on the "key" size versus the size of the message. If the "key" is "smaller/shorter" than the message, then that might be useful. There's a great lecture on this site by Microsoft computer scientists explaining the math of it all. It's under 2 hours and is actually *very* approachable.

Sigh... no. Except for maybe something like a cypher key to decrypt information.

Bob can now ace his exam without even looking at his test.

It's important to note that quantum teleportation is not a cloning technique. If for example quantum teleportation techniques are ever advanced to the point where all the information about a physical object can be extracted and used to recreate an exact copy of the object at a different location, then the process of extracting that information will in effect destroy the original (or at least leave it in state that is unrecognizable from its original state).

No, anyone can do it. It takes a true expert to get it right. In the case of physics, almost all physicists get something wrong when it comes to explaining QM experiments for the simple basic reason that our natural physical intuition was not created by functioning the tiny domain of the atom or smaller. It took me a long time to accept such widespread ignorance in physics, because it attempts to be so rigorous and because its primary tool is mathematics, which actually is rigorous and always correct since it is based on the concept of proof. Physics is necessarily based on theory, observation, and correction (the scientific method).

What a lot of people do not understand is that a particle's spin is determined when it is measured. The spin of the entangled particle is locked in when the first particle is measured, no matter how far away the entangled particle is. As far as Relativity and simultaneity goes there are odd implications.

[@gordonstanley7802]

How do you know that it could not already be a property before it is measured? In fact the idea that it is some random value chosen when the measurement takes place seems absurd. It is more like this. Two people meet and one gives a specific amount of money to the other. If I measure one of them (i.e ask them how much they are in debt or owed) then it tells me the state of the other. I think maybe you just are not expressing yourself correctly. It is not determined when it is measured, it becomes known when it is measured.

[@etialpti9930]

Really missed the "yes, this guy again"

[@aresh004]

question: suppose that the sender and the receiver plan out far in advance exactly what measurement types they will do on what entangled pairs. with this sort of pre scripting, could quantum teleportation then be used to send new inormation faster than light?

[@loweel2897]

information cannot travel faster than light, on the other side, you don't' need to know how fast it travels.

[@SabineHossenfelder]

No, you need the measurement outcome from one side and send it to the other side. You don't know what the outcome is in advance.

[@tetraedri_1834]

To further elaborate, sequence of measurements needed to be done on the receiver side depends on the measurement outcome in the sender side. So it doesn't help receiver at all to know what sender does

[@georgelionon9050]

No you can't, because you can't force the outcome of the measurement. But if the sender and receiver later meet up and compare notebooks, they'll see that they match.

[@quickmana]

I was thinking it still wouldn't be faster than light because of the information exchange that took place earlier happened slower than light, but still an interesting idea to turn something small into something big -- quantum compression? :)

I thought entanglement was just a form of correlation, while "spooky action at a distance" referred to the collapse of the waveform for any measurement.

[@valentinmalinov8424]

Quantum entanglement is very easy to be understood. If you are interested, just find my book - "Theory of Everything in Physics and The Universe"

[@jamestheotherone742]

Yes. "spooky action at a distance" was a singularly poor analogy for the concept Einstein was trying to express. Almost as bad as Schrodinger's Cat. It enabled quantum mechanics literalism instead of disputing it as was intended.

@@jamestheotherone742 That's what Sabine explained in an earlier video about the measurement getting updated rather than the entanglement itself.

Thank u so much for doing this

[@MarcSylex]

Would be nice to know what the "measurement" actually entails. Is it just some numerical value or is it some complicated value expressed as a function? This always bugged me.

Probably something like "Do you measure the polarisation in the horizontal or the vertical axis".

Trying to define reality with QM is equivalent to trying to describe the ocean by studying fish and seaweed.

Perhaps. And there is no alternative.

[@valentinmalinov8424]

Quantum Mechanics start to make sense only if you have correctly defined fundamental elements. Modern science is using incorrect defined fundamental elements and is running in "puzzles" and "mysteries" Quantum entanglement is very easy to be understood.

The 'ocean' includes the Higgs Boson, the Higgs field, dark matter, dark energy, the 'vacuum', black holes, the ultra cold, gravitational waves and mass, none of which have a quantum definition.

"no superdeterminism" is one of the assumptions for Bell's theorem. So with superdeterminism, it doesn't work, basically.

That's right. I mentioned "spooky action at a distance" after I talked about the measurement, which is the same I said in my earlier video.

[@peterzerfass4609]

Quantum encryption seems to me one of the most beautiful ways to demonstrate that encryption does not add information (and hence the use of quantum teleportation to enable quantum encryption does not violate the lightspeed limit of (classical) information transmission)

[@peterowens290]

Sorry but I have to say this is not a very revealing contribution. It seems that Sabine has stirred a hornets nest of ambiguity, incomplete concepts & a dearth of experimentally established fact. Even the issue to light speed violation (or not) is not well presented.

[@Verlamian]

Tut tut! There are two serious conceptual errors in that description of EPR(B). Firstly, it fails "the ping pong ball test": there's nothing peculiar about bipartite systems having (antii-)correlated properties no matter how far apart the component systems are. In order to grasp what's interesting about the quantum - entangled - case it's crucial to understand that for entanglement to occur it's necessary that there be (at least two) incompatible observables of each component involved. Secondly, and relatedly but slightly more subtly, it's important to understand that it's not true that the outcome of the observation on one component system determines the *value* of the corresponding property on the other. It determines the *outcome* of the corresponding measurement *if that measurement is done*.

@Parker Sullins and if everyone thought that way no one would be an NBA player, I’m in my first year of a physics PhD and I very much hope that one day I’ll advance the field (even in just some small way) but if I turn out to not have that intuitive spark to make a difference then I’ll happily turn to teaching what I do know and understand in the hopes that the next generation will figure out what I could not.

[@jongya]

@Parker Sullins one of the things I love about physics and science in general is that everyone can participate. Even if someone can’t make the intuitive leaps to discover something new, I’d say everyone has the ability to learn what’s already been discovered it’s just a matter of hard work and interest. Keeping people as receptacles for information they can distribute may not be as flashy as exploration but it’s still an important wonderful contribution to humanity
