We propose and analyze a robust quantum state transfer protocol through a scalable quantum data bus that consists of a network of controlled dissipative modules. In particular, we first demonstrate the ability to achieve perfect state transfer between two distinct quantum sites which are adiabatically coupled to the data bus in non-dissipative situation. We then consider the role of dissipation in adiabatic quantum state transfer via using Born–Markov master equation in the standard Lindblad form. Numerical simulation shows that the dissipation effect on the quality of transmission can be suppressed by engineering the network couplings of data bus properly.

通过耗散量子数据总线的高保真量子态传输

我们提出并通过可扩展的量子数据总线（由受控耗散模块网络组成）分析鲁棒的量子状态传输协议。特别地，我们首先展示了在非耗散情况下绝热耦合到数据总线的两个不同量子点之间实现完美状态转移的能力。然后，我们通过使用标准Lindblad形式的Born-Markov主方程来考虑耗散在绝热量子态转移中的作用。数值模拟表明，通过适当设计数据总线的网络耦合，可以抑制对传输质量的耗散影响。
