论文摘要
保持量子相干性是量子计算领域的基本挑战。在这里，我调查了在经典环境中经历局部dephasing的Qubits的冷冻不和谐现象和非马克维亚语。可以在有限的时间内冻结特定初始两分状态的量子不一致，即与随机高斯田地独立相互作用。不和谐的保存被证明与信息从环境的回流密切相关。比较了量子驱动环境的相关结果。
Preserving quantum coherence is fundamental challenge in the field of quantum computation. Here, I investigate the frozen discord phenomenon and non-Markovianity for qubits experiencing local dephasing in a classical environment. The quantum discord of a certain initial bipartite state, independently interacting with stochastic Gaussian fields, can be frozen for a finite time. The preservation of discord is shown to be intimately related to the backflow of information from the environment. The relevant result for quantum dephasing environment is compared.
