On the Experimental Determination of Nonlocal Characteristics of Two-Qubit Gates
M. Karthick Selvan, S. Balakrishnan
The paper proposes experimental quantum circuits that use native two‑qubit interactions and CNOT gates to directly measure the entangling power and gate typicality of two‑qubit gat…

Optimal Construction of Two-Qubit Gates using the Symmetries of B Gate Equivalence Class
M. Karthick Selvan, S. Balakrishnan
Two applications of gates from the B gate equivalence class can generate all two-qubit gates. This local equivalence class is invariant under the mirror (multiplication with the SW…

Characteristics and Implementation of B Gates
M. Karthick Selvan, S. Balakrishnan
In this brief report, we discuss the characteristics of B gates. We provide the conditions for the two-qubit gates generated by two applications of a B gate. We propose a…
