利用核磁共振模拟纠缠态系统的退相干行为

Simulating decoherence behavior of a system in entangled state using nuclear magnetic resonance

Jingfu Zhang, Zhiheng Lu, Lu Shan, Zhiwei Deng

摘要:

选取13碳标记三氯乙烯中的H核作为单量子比特环境,两个C核作为双量子比特系统,利用核磁共振(NMR)方法模拟了系统处于纠缠态时的量子退相干.解耦技术用于跟踪环境自由度。实验结果与理论预测一致。我们的实验方案可以推广到由多个量子比特组成的环境。

英文摘要:

By choosing H nucleus in Carbon-13 labelled trichloroethylene as one qubit environment, and two C nuclei as a two-qubit system, we have simulated quantum decoherence when the system lies in an entangled state using nuclear magnetic resonance (NMR). Decoupling technique is used to trace over the environment degrees of freedom. Experimental results show agreements with the theoretical predictions. Our experiment scheme can be generalized to the case that environment is composed of multiple qubits.
