Nice article discussing possibility of building quantum computers on topological defects in liquid crystals: https://arxiv.org/pdf/2008.13094

There was demonstrated e.g. interference ( https://journals.aps.org/prb/abstract/1 ... .85.094503 ), tunneling ( https://journals.aps.org/prb/pdf/10.110 ... B.56.14677 ), Aharonov-Bohm ( http://www.tau.ac.il/~yakir/yahp/yh33 ) for fluxons - topological defects in superconductor.

Here is de Gennes' " An analogy between superconductors and smectics A": https://www.sciencedirect.com/science/a ... 987290186X

So could we violate Bell, build quantum computers on such "macroscopic quantum phenomena"? ( https://en.wikipedia.org/wiki/Macroscop ... _phenomena )
