Exact two-qubit universal quantum circuit
Jun Zhang, Jiri Vala, Shankar Sastry +1
We provide an analytic way to implement any arbitrary two-qubit unitary operation, given an entangling two-qubit gate together with local gates. This is shown to provide explicit c…

A geometric theory of non-local two-qubit operations
Jun Zhang, Jiri Vala, K. Birgitta Whaley +1
We study non-local two-qubit operations from a geometric perspective. By applying a Cartan decomposition to su(4), we find that the geometric structure of non-local gates is a 3-To…
