论文摘要
我们描述了使用与远距离相互作用的哈密顿动力学执行量子状态转移的有效协议。转移$ n $ Qubits的时间与$ \ sqrt {n} $成正比。即使没有误差校正,在耦合常数中存在不相关的随机误差的情况下,这种多量状状态转移过程的保真度仍然有限。
We describe an efficient protocol to perform quantum state transfer using Hamiltonian dynamics with long-range interactions. The time to transfer $n$ qubits a sufficiently large distance is proportional to $\sqrt{n}$. Even without error correction, the fidelity of this multi-qubit state transfer process remains finite for arbitrarily well-separated qubits in the presence of uncorrelated random errors in coupling constants.
