Generators and Relations for Un(Z[1/2,i])
Xiaoning Bian, Peter Selinger
Consider the universal gate set for quantum computing consisting of the gates X, CX, CCX, omega^dagger H, and S. All of these gates have matrix entries in the ring Z[1/2,i], the sm…

Techniques to Reduce -Parity-Phase Circuits, Motivated by the ZX Calculus
Niel de Beaudrap, Xiaoning Bian, Quanlong Wang
To approximate arbitrary unitary transformations on one or more qubits, one must perform transformations which are outside of the Clifford group. The gate most commonly considered…
