On the Experimental Determination of Nonlocal Characteristics of Two-Qubit Gates
M. Karthick Selvan, S. Balakrishnan
In this paper, we discuss the experimental determination of the nonlocal characteristics of two-qubit gates. Based on the recently derived expressions for the entangling power and…

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 an…
