Classical physics and quantum physics can not understand Hardy's paradox



Physicists have given more substance to Hardy's paradox, suggesting that the discrepancy between classical physics and quantum physics is even greater than previously thought.

Lucien Hardy is Professor at the Perimeter Institute of Theoretical Physics in Waterloo, Canada.

In 1993, Hardy proposed a thought experiment to prove the nonlocality principle in quantum physics

This experiment was first known as Hardy's paradox. Some argue that, strictly speaking, it is not a paradox, such as the Einstein-Podolsky-Rosen Paradox . In many ways, it's more of a theorem.

In the universe, when matter and antimatter meet, particles and antiparticles annihilate each other with an energy current in the form of gamma rays.

Hardy has shown this, however. It is theoretically possible that sometimes (in 6 to 9 percent of cases), when no observer is present, matter and antimatter can interact and survive the encounter ̵

Towards a Generalized Hardy Paradox

Physicists experimentally demonstrated the Hardy paradox with two particles. They also believe that it is valid even with more than two particles, although they could not fully demonstrate it.

Now, an international research team was able to demonstrate Hardy's paradox with three particles in an experiment that they say could be extended (19659003) With three particles, the probability of researchers seeing paradoxical cases increased to 25 percent at .

This experiment suggests that the Hardy paradox could be generalized, meaning that the schism between classical and quantum physics could be even deeper.

Jing-Ling Chen, co-author of the study, told Phys.org:

"In this article we show a family of generalized Hardy's paradox most, by not just previously known by adapting certain parameters It also highlights sharper conflicts between quantum and class theories in general, and based on the paradoxes we can also write down novel Bell's inequalities that allow us to discover more quantum-entangled states. "

Simple said Bell's Theorem aims to find correlations between two separate

Bell built on the Einstein-Podolsky-Rosen paradox and showed that the quantum mechanical phenomena can not be interpreted within a realistic local framework.

"Put simply," Chen explains, "Hardy's paradox says that a classically impossible sequence of events is end-to-end – imagine a snake devouring its tail – so to speak, is inexorably possible in the quantum region is really surprising. "

The team plans to further explore the relationship between Bell's theorem and Hardy's paradox.

The results of the experiment are available in arXiv.org
