利用超图态实现任意单、双量子比特态的量子隐形传态

Experimental realization of quantum teleportation of arbitrary single and two-qubit states via hypergraph states

Atmadev Rai, Bikash K. Behera

摘要:

在这里,我们展示了量子隐形传态通过超图态,这是图态的推广,由于其非局域纠缠特性,它允许我们执行量子隐形传态。本文设计了几种可用于量子隐形传态的超图态,并分别利用三个均匀的三量子比特超图态和四量子比特超图态实现了单量子比特和两量子比特任意态的量子隐形传态。阐述了单比特和双比特任意态的量子隐形传态的实验实现。然后,我们在IBM量子体验平台上运行我们的量子线路,在那里我们展示了模拟器和真实设备(如“ibmq_qasm_simulator”和“ibmq_16_melbourne”)获得的结果,并计算保真度。我们观察到实际器件与模拟器相比存在一些误差,这些误差是由于量子信道中的退相干效应和门误差造成的。然后,我们说明了实验和理论的密度矩阵的隐形传态的单和双量子比特状态。

英文摘要:

Here we demonstrate quantum teleportation through hypergraph states, which are the generalization of graph states, and due to their non-local entanglement properties, it allows us to perform quantum teleportation. Here we design some hypergraph states useful for quantum teleportation and process the schemes for quantum teleportation of single-qubit and two-qubit arbitrary states via three-uniform three-qubit and four-qubit hypergraph states respectively. We explicate the experimental realization of quantum teleportation of both single and two-qubit arbitrary states. Then we run our quantum circuits on the IBM quantum experience platform, where we present the results obtained by both the simulator and real devices such as "ibmq_qasm_simulator" and "ibmq_16_melbourne" and calculate the fidelity. We observe that the real device has some errors in comparison to the simulator, these errors are due to the decoherence effect in the quantum channel and gate errors. We then illustrate the experimental and theoretical density matrices of teleported single and two-qubit states.
