在ibmq-melbourne量子计算机上制备薛定谔猫态及其纠缠研究
Preparation and study of the entanglement of the Schrödinger cat state on the ibmq-melbourne quantum computer
摘要：
我们研究了在ibmq-melbourne量子计算机上制备的薛定谔猫态中某个量子比特与剩余系统之间的纠缠。我们用于此目的的协议是基于确定对应于某个量子位的自旋的平均值。我们探讨了纠缠对薛定谔猫态的一个参数的依赖关系，该猫态由不同数量的量子比特组成。此外，我们还研究了在最大纠缠薛定谔猫态下，每个量子比特与剩余系统的纠缠。
英文摘要：
We study the entanglement between a certain qubit and the remaining system in the Schrödinger cat state prepared on the ibmq-melbourne quantum computer. The protocol, which we use for this purpose, is based on the determination of the mean value of spin corresponding to a certain qubit. We explore the dependence of the entanglement on a parameter of the Schrödinger cat state which consists of different numbers of qubits. In addition, we explore the entanglement of each qubit with the remaining system in the maximum entangled Schrödinger cat state.
