Optimal Control of Two-Qubit Quantum Gates in a Non-Markovian Open System

摘要

Based on the exact non-Markovian master equation for two interacting two-level atoms coupled to a dissipative zero-temperature bonsonic environment, we extend the results of Tai [Phys. Rev. A 89, 062310 (2014)], in which optimal control approach is used to implement one-qubit gates within the same environment, to two-qubit gate implementations with the help of Krotov's iterative method for optimal control. Furthermore, for practical applications, the realization of a quantum circuit comprising cascaded quantum gates is considered.
