论文摘要
我们描述了一种在固定的,工程化的哈密顿式的动态下将量子状态从一个方完美传递到另一方的协议。我们的协议结合了分数复兴,双轨编码的概念,以及对抗Zeno效应的罕见瞥见。值得注意的是,转移的发生速度快于完美量子状态转移的速度极限[1,2]。
We describe a protocol for perfectly transferring a quantum state from one party to another under the dynamics of a fixed, engineered Hamiltonian. Our protocol combines the concepts of fractional revival, dual rail encoding, and a rare glimpse of the anti-Zeno effect. Remarkably, the transfer happens faster than the speed limit for perfect quantum state transfer [1, 2].
