A quantum simulator of impossible physics

October 8, 2015, University of the Basque Country

The research group Quantum Technologies for Information Science (QUTIS) of the UPV/EHU-University of the Basque Countr has created a quantum simulator that is capable of creating unphysical phenomena in the atomic world—in other words, impossible physical phenomena. The researchers have succeeded in getting a trapped atom to imitate behaviours that contradict its own fundamental laws, thus taking elements of science fiction to the microscopic world.

"We have managed to get an atom to act as if it were infringing the nature of atomic systems, in other words, quantum physics and the theory of relativity. It is just like what happens in the theatre or in films in which the actors appear to display absurd behaviours that go against natural laws; in this case, the atoms are obliged to simulate absurd actions as if an actor in the theatre or in science fiction were involved," explained Prof. Enrique Solano.

The results of this research have been published in the prestigious journal Nature Communications. The research team of the UPV/EHU's QUTIS group has been led by Prof Enrique Solano and has had the participation of Dr Lucas Lamata and Dr Jorge Casanova, currently at the University of Ulm, Germany.

In this experiment, the researchers reproduced in the lab the theoretical proposal previously included in research led by the QUTIS group; it describes the possibility that a trapped atom can display behaviour that is incompatible with the of . More specifically, it deals with operations prohibited in microscopic physical systems such as charge conjugation, which transforms a particle into an antiparticle, or time reversal, which reverses the direction of the time arrow.

To conduct the experiment, it was necessary to use a charged atom trapped by means of electromagnetic fields under the action of an advanced laser system. Symmetry operations of this type are described as prohibited ones, as they could only exist in a universe that is different from the one we know and are governed by different laws. Yet, in this experiment, it has been possible to simulate this set of impossible laws in an atomic system.

The UPV/EHU's QUTIS group is a world leader in quantum simulation and its influential theoretical proposals are often verified in the most advanced quantum technology laboratories. In this case, physical operations that are prohibited for the atomic world can be reproduced just as in science fiction—in other words, just as if they were taking place artificially in a quantum theatre.

Three dimensions provide a special property: The ability to emulate higher dimensions, albeit less efficiently than an actual higher dimensional system.

Three dimensions of space plus one dimension of time is sufficient to emulate any higher dimensional system, or any system with different laws, therefore it does not surprise me that under certain controlled circumstances you could produce a system which follows different laws temporarily, so long as there is a "super-set" of the system which follows the laws of the universe on the whole, and follows the laws of thermodynamics on the whole.

so I'm saying from mathematical modeling, it should be possible to build a machine which temporarily violates the laws of physics, so long as the logic of the math is sound, and so long as the final result obeys the laws of physics on the whole.

I guess what I'm saying is Newton's laws were derived under the assumption that space was continuous and matter behaved in classical ways.

The laws of physics, and even quantum laws, may not hold for literally all of space and time. I'm not suggesting chaos by any means, but with sufficient manipulation it may be possible to produce systems which temporarily obey different laws of physics.

This probably wouldn't happen in nature (not very often anyway) because nature tends to go from order to disorder (second law). In design we go from less order to more order in a sub-system, but the "super-system" goes from less order to even less order as that change happens. Classic example being the entropy of the Sun vs the organization of life on Earth.

However, I propose that their might be a valid mathematical scenario where the entropy of the Sun goes down temporarily, for lack of a better example.

macroscopic teleporters and worm holes may one day be possible.

If some "impossible" state appears in some system, and immediately creates a disturbance that propagates at the speed of light...

The "information" it leaves behind, say minor gravitational fluctuation, heat waste, etc, would add to the ultimate Entropy of the universe and so not violate the 2nd law of thermodynamics.

Moreover, as long as all forms of energy and momenta introduced cancel, then it does not violate any conservation laws, at least as stated. So for example as long as two photons produced in this manner have equal and opposite momenta, then the laws are ultimately obeyed.

however, I believe something cannot come from nothing as being a fundamental logical precept, so that all things which have existed or can exist in the universe must arise from "something" which already exists, beit a background media in the existing universe, or from God, or whatever, but it can't logically just "come from absolute nothing".

I was banned from another physics forum again yesterday within 2 posts for discussing a problem with the definition of "Energy" under the present regime of Relatvistic gravity, and also for proposing my hypothesis that "Gravitational Waves" degenerate into infrared due to internal friction in the background media of space-time.

They said I violated their rules. Aparently these two hypothesis somehow violate their terms of use policy.

I'm like, "wtf...internal friction is a well known concept in physics, all I did was apply it to a new media: space-time itself."

My hypothesis is as good as any for why we don't detect gravitational waves directly (LIGO) even though the gravitational wave formula correctly predicts black hole and neutron star orbital decays.

In fact, I haven't even seen anyone else offer a viable hypothesis as to why this apparent contradiction should happen. My hypothesis resolves the contradiction without major changes to physics.

I even told them what to look for in order to find evidence to support my hypothesis.

What is my "reward" for this contribution?

I get banned from the physics site by the administrator.

The stuck up asshole probably never thought of anything that insightful in their life.

I've mentioned it here several times before, so if someone tries to steal my ideas and publish as their own, all I'll need to do is search the physorg archives for my own comments and sue their ass.

Hey "Peer review" crowd:

This is why "Settled Science" is so flawed. This is why a Sophomore Engineering student can find a very basic way to improve Lithium Ion batteries that the "experts" over-looked for 20 years.

One of the biggest problems in science and engineering right now is the RIGID THINKING of the scientists themselves.

The freaking administrator of that site should be banned, not me.

They wouldn't know how to do real science if it bit them in the ass.

It would be easier to think like a quantum! Let's define a quantum relative to a charge at [x1 x2 x3 x4], in a 4D space, units isomorphic to lambda of lambda nu = c. This point is the normal vector of the hyper-sphere about a charge or defined as a charge that would otherwise exist to create this field of 1/(4*Pi*r^2). Poynting Vector, need anything else? Make your own movie! Call it "Wizard's Palace!"

Choose a perspective, don't leave it to number theory.

Hyperfuzzy:
If we can build a virtual engine which simulates laws of physics in higher dimensions on a computer, then maybe we can make a machine which temporarily enforces those laws on the real world, or manipulates the existing laws to get the same effect...

a "Stargate" for example.

Maybe a "Time Bubble"....

Why? slow down or speed up time for a newly discovered planet, so that it evolves at a different rate with respect to the rest of the universe. To play "catch-up"? or to preserve forever?

How to actually do that? I have no clue.

However, given enough energy and the right circumstances, I see no reason such machines couldn't one day be made, as they don't violate any universal law, even though they appear to violate the law locally.

You said the same thing in many different ways and in the end didn't say much...

What exactly is happening? What are the implications? Can we extract more energy than is put into the system? Send information back in time? Did one of the scientists got stretchy, the other invisible, her brother caught fire, and another guy got hard?
