Abstract

A system consisting of two qubits and a resonator is considered in the presence of different sources of noise, bringing to light the possibility of making the two qubits evolve in a synchronized way. A direct qubit-qubit interaction turns out to be a crucial ingredient, as well as the dissipation processes involving the resonator. The detrimental role of the local dephasing of the qubits is also taken into account.

摘要

研究了一个由两个量子比特和一个谐振器组成的系统，该系统存在不同的噪声源，揭示了使两个量子比特以同步方式演化的可能性。结果表明，直接的量子比特-量子比特相互作用以及涉及谐振器的耗散过程是关键因素。同时也考虑了量子比特局部退相的有害作用。
