Minimum construction of two-qubit quantum operations
Jun Zhang, Jiri Vala, Shankar Sastry +1
Optimal construction of quantum operations is a fundamental problem in the realization of quantum computation. We here introduce a newly discovered quantum gate, B, that can implem…

Optimal quantum circuit synthesis from Controlled-U gates
Jun Zhang, Jiri Vala, Shankar Sastry +1
From a geometric approach, we derive the minimum number of applications needed for an arbitrary Controlled-Unitary gate to construct a universal quantum circuit. A new analytic con…
