And above all we do not yet have the OS that allows you to get the quintessence of this type of computer and even less the software optimized for this new technology.

An international team of researchers has succeeded in reversing the entropy of a fraction of a second on a quantum computer.

Researchers have come up with a surprisingly surprising experiment that could help improve quantum computing in the years to come. The team of physicists "tweaked the state of a (tiny) quantum computer by a fraction of a second" by reversing the process of entropy in a two- and three-qubit system.

Entropy and disorder

The second principle of thermodynamics states that "the total entropy of an isolated system can never decrease". This somewhat barbaric statement amounts to saying, in a schematic way, that a system (in this case, our Universe) is doomed to advance towards an increasingly disorderly state, a bit like the milk and the coffee of a café. milk become more difficult to separate as the two liquids mix.

The "arrow of entropy" is modeled on the "arrow of time". It is the changes brought about by entropy, this irreversible growth of disorder, that we perceive as the passage of time according to researchers. Traveling in time would therefore, in theory, reduce the total entropy, which would constitute a violation of the second principle of thermodynamics.

Inversion of entropy

"In December, we published an article that addresses the violation of the second principle of thermodynamics using a method called Maxwell's demon," said Gordey Lesovik, lead author of the study. "We have artificially created a state that moves in the opposite direction of the arrow of thermodynamic time." This counterintuitive state has been observed in action with an 85% success rate in a two-qubit system.

On a small scale and very locally the entropy can be reversed, on the other hand globally it can only increase. However, nothing says that this increase is immutable, in particular within the framework of a cyclic theory of the Universe or of quantum gravity.

still a big comm scam, reversing the sense of time "at the local level" does not mean that the entropy of the Universe decreases, they do not count all the energy consumed by the device around! it is the solution of Maxwell's demon paradox, to measure microscopic information on a system, we must accept to dissipate more of it outside.

But hey Americans are always looking for funds, so they always have an interest in presenting their research in a "inflated" way!

Moreover, it has been a long time since time reversal experiments were carried out by "spin echo" which also seem to reverse the direction of time.

For almost 2 years, they must have found them, right?

China, not Google, now owns the world's most powerful quantum computer

(...)

Google's processor had 54 qubits and solved a benchmark problem in just 3 minutes and 20 seconds. The Google team claimed that it would take 10 years for the world's most powerful supercomputer to solve this same version of the problem, although IBM later claimed that its classic supercomputer could have solved it in two days and half, but did not demonstrate it in practice.

The Chinese processor, named Zuchongzhi (after the 800th century mathematician Zu Chongzhi, who calculated Pi with an accuracy that would not be exceeded for 66 years), meanwhile has 56 qubits, but the team does not have any. used only 70 in the experiment, solving the problem in about XNUMX minutes. The researchers claim in their paper that this is an "unambiguous" demonstration of quantum supremacy.
