论文摘要
尽管不可能对未知量子状态进行完美的复制,但量子力学中可能进行了近似克隆。量子触发器是近似量子克隆的一种变体,它使用量子传送带允许使用经典通信来创建量子状态的物理分离克隆。我们介绍了$ 1 \ rightarrow的结果9 $通用,对称,最佳的量子telecloning实现在云可访问的量子计算机 - Quantinuum H1-1设备上。 H1-1设备允许直接创建遥控协议,这是由于实时经典的IF statement在铃铛测量的中路测量结果上有条件的效果。在此实施中,我们还为量子遥控的电路模型描述提供了对以前的工作的改进,从而减少了所需的栅极深度和栅极计数,以实现全能连接。在量子处理器上创建$ 9 $近似克隆的演示是生成,遥控或其他方式的最多克隆。
Although perfect copying of an unknown quantum state is not possible, approximate cloning is possible in quantum mechanics. Quantum telecloning is a variant of approximate quantum cloning which uses quantum teleportation to allow for the use of classical communication to create physically separate clones of a quantum state. We present results of a of $1 \rightarrow 9$ universal, symmetric, optimal quantum telecloning implementation on a cloud accessible quantum computer - the Quantinuum H1-1 device. The H1-1 device allows direct creation of the telecloning protocol due to real time classical if-statements that are conditional on the mid-circuit measurement outcome of a Bell measurement. In this implementation, we also provide an improvement over previous work for the circuit model description of quantum telecloning, which reduces the required gate depth and gate count for an all-to-all connectivity. The demonstration of creating $9$ approximate clones on a quantum processor is the largest number of clones that has been generated, telecloning or otherwise.
