Time-Optimized Generation of Two-Qubit Entanglement States

Abstract

Abstract:

A time-optimized method to control the unitary time evolution in a quantum unitary gate was proposed using the Heisenberg model. For two classes of states |00〉，|11〉 and |01〉，|10〉, the time-optimized generation of any target entangled state under a uniform magnetic field was analyzed, and a novel strategy based on the time-optimized method to generate two qubit entangled states was suggested. The effectiveness of the proposed strategy was theoretically verified by simulations.

Key words: unitary gate, entangled states, time-optimized, generation of entangled states
