How Physicists Created a Holographic Wormhole in a Quantum Computer

(1/4) > >>

BrianHG:
Can someone please explain to me exactly what these scientists have actually done...



I'm trying to wrap my head around that they moved or created 2 entangled, I guess you could call it each end of a wormhole, and id doing so, they observed an effect which only negative mass energy could be the explanation.  Something which is required to maintain a wormhole, however, as far as we know, does not exist in our universe.

Am I on the right track?
Or, did they go even a step further by passing a Q-Bit of information through that wormhole.

Rick Law:
Looks like what they have successfully done is to use "digital" quantum computer in an "analog" way, and applied that to simulate the properties of wormholes (to some degree).  The simulation give us further insight into how wormholes may behave.


For example, looking at force of gravity and force of electrical attraction, they look identical:

For gravity force, F = G*M1*M2 / (R*R)
For electrical force , F = K*Q1*Q2 / (R*R)

If you have a computing machine that operates based on electrical charges and distance with measurement of the electrical attraction force as the result, you can use that device to evaluate gravitational attraction force.  Such a computing could be called an analog computer for gravitational forces.  You adjust the Q and R (in scaled form) for M and R, and the resulting electrical force as measured.  With proper scaling, you have the gravitational force instantaneously.

Slide-rule is another analog computing device.  Using additive property of length and use logarithm property of "adding log of two number is same as multiplying", slide rule can multiply numbers easily by merely adding the lengths with individual length markers done in logarithm scale.

It is currently accepted mathematically quantum entanglement is identical to worm holes' math.  So one can be the analogy of the other.  Quantum computers use quantum entanglement and so it is rather convenient to use that to simulate the other similar phenomenon with identical math -- namely, wormholes.  That the two different phenomenon have the same math may not mean the two phenomenon are the same.

For gravity and electrical forces, there are certainly indication that all known forces could be unified.  Einstein worked on "Unified Field Theory" for much of his later career.  Currently, it is generally assumed  that the forces are unified at the beginning and separated as the universe cools.  How same are they now is certainly still a valid question -- note the development of "Modified Gravity" in-lieu of  "Dark Matter" in Cosmology.

Mathematics is a form of representation of Physical phenomenon.  Are they the same can be more Metaphysics than Physics.

One other question, that they can do some simulation is a success to some degree, but how much can they really simulate is another.

BrianHG:
@Rick Law, so what you are saying is that they setup the quantum computer hardware to simulate the function of a wormhole in a 'quasi' physical way and in turn when applied, the computer reveals a result that the effect of some negative energy is 'revealed'.

Basically this is like saying either A/B/C, or any combo:
 A) That our math about the physics functions and if we wanted to create a spacial, negative energy is a requirement which we cannot yet create in any way.
 B) In our universe, entangled particles which are theoretically linked by micro-wormholes, must contain a tiny amount of negative energy, not yet observed, to maintain the entanglement.
 C) As theorized, you may not need negative energy to maintain the wormhole / quantum entangled particles, but to be able to traverse / sen matter through one, you need the 'unobtanium' negative energy to keep it open to send anything through.


For option C, if you have 2 solid surfaces with each constructed with perfectly maintained quantum entangled particles, with the addition of enough negative energy, you might be able to construct a traversable wormhole.  Though I'm guessing this negative energy would need to be absurd, like the equivalent mass energy of the matter being sent through squared.

RoGeorge:
Quanta Magazine is a written magazine, and sometimes the articles have an embedded video to augment the text.
The video without text might not make much sense (as a standalone video).  The video you linked is from this article:
https://www.quantamagazine.org/physicists-create-a-wormhole-using-a-quantum-computer-20221130/

Even together with the article, might still not make much sense.  From my experience (followed them for a while 1-2 years ago), I found their articles too long, with too much journalism, and not clear about the scientific part, at least for me.  Never learned anything from their articles, only that they were hyped about whatever research.  If interested about something they present, skip the article/video, and read the research paper even if it's not your specialty, the paper will give a better clue than the article.

vad:
Quantum computers are built with state of the art sources of entangled particles that are best at mitigating issues like quantum decoherence. I assume the researchers found some ingenious way of testing ER=EPR conjecture using quantum computers’s hardware, in particular the sources of entangled particles and detectors.

I do not think the experiment had anything to do with quantum computing algorithms. The team might have just repurposed the computer for the experiment. But I am not expert, and could be wrong.
