研究了由一组玻色子场模式介导的两个量子比特的相干演化。通过假设量子比特内部能级中量子态的特定非对称编码,我们表明即使涉及大量中介模式,也可以以高保真度实现纠缠量子门。还详细讨论了损耗和缺陷对栅极工作的影响。
The coherent evolution of two qubits mediated by a set of bosonic field modes is investigated. By assuming a specific asymmetric encoding of the quantum states in the internal levels of the qubits, we show that entangling quantum gates can be realized, with high fidelity, even when a large number of mediating modes is involved. The effect of losses and imperfections on the gates' operation is also considered in detail.
