On Clifford hierarchy testing and near-extremizers of noncommutative uniformity norms
Zongbo, Bao, Jop Briët +3
We consider the problem of testing whether an unknown unitary is close to a specified level of the Clifford hierarchy. Bu, Gu, and Jaffe proposed a candidate tester for this task b…

Symmetric quantum computation
Davi Castro-Silva, Tom Gur, Sergii Strelchuk
We introduce a systematic study of "symmetric quantum circuits", a new restricted model of quantum computation that preserves the symmetries of the problems it solves. This model i…
