Characterization of permutation gates in the third level of the Clifford hierarchy

Zhiyang He, Luke Robitaille, Xinyu Tan

The Clifford hierarchy is a fundamental structure in quantum computation whose mathematical properties are not fully understood. In this work, we characterize permutation gates --…

Unitary synthesis with fewer T gates

Xinyu Tan

We present a simple algorithm that implements an arbitrary $n$ -qubit unitary operator using a Clifford+T circuit with T-count $O (2^{4 n /3} n^{2/3})$ . This improves upon the previous…
