Is quantum computer applicable or not? Although so many scientists and engineers devote a lot in the field, it is not generally agreed in academics. This is just one of them.
To solve the Heisenberg Hidden Subgroup problem more efficiently by Clebsch-Gordan transform, a problem whose classical query complexity is exponential.
It is about quantum spin hall effect (QSH), although I could not access the article. According to the author, [QSH] can be realized in mercury telluride–cadmium telluride semiconductor quantum wells.
Quantum Computing has not initiated any private discussions.
