We propose a bio-inspired sequential quantum protocol for the cloning and preservation of the statistics associated to quantum observables of a given system. It combines the cloning of a set of commuting observables, permitted by the no-cloning and no-broadcasting theorems, with a controllable propagation of the initial state coherences to the subsequent generations. The protocol mimics the scenario in which an individual in an unknown quantum state copies and propagates its quantum information into an environment of blank qubits. Finally, we propose a realistic experimental implementation of this protocol in trapped ions.
我们提出了一种受生物启发的量子序列协议,用于克隆和保存与给定系统的量子可观测量相关的统计信息。它将无克隆定理和无广播定理所允许的一组对易可观测量的克隆,与初始态相干性到后续世代的可控传播相结合。该协议模拟了这样一种情形:处于未知量子态的个体将其量子信息复制并传播到空白量子比特的环境中。最后,我们提出了在囚禁离子中对该协议进行实际实验实现的方案。
