摘要

本研究包含两个远距离克隆协议，用于在两个遥远的地点获得类似贝尔状态的近似克隆拷贝。第一个是利用 ancilla 量子位的通用远程克隆程序，而在第二个协议中，不需要 ancilla 量子位。对克隆副本质量的保真度进行了分析。这两个协议都是在 IBM 平台上使用 Aer 模拟器和量子真实计算机执行的。通过比较这两种情况的结果，我们得出结论：这两个协议都很稳健。

Two protocols for telecloning of Bell-like states with and without ancilla qubit

The present work contains two telecloning protocols for obtaining approximately cloned copies of Bell-like states at two distant locations. The first one is a universal telecloning procedure utilizing ancilla qubits while in the second protocol, no ancilla qubit is required. The analysis of fidelity measuring the quality of the cloned copy is presented. Both the protocols are executed on the IBM platform using Aer Simulator as well as on quantum real computers. By comparing the outcomes of these two cases we conclude that both the protocols are robust.
