论文摘要
如其他地方所示，量子计算中发生的纠缠或相关性丧失或相关性的合理模型是，它假定它们可以通过一个框架有效地预测，该框架以系统内部的不可逆性为前提。它基于最陡峭的浓度原理，此处用于与实验数据相吻合，从而重现受控相位门的行为。结果表明，预测的纠缠损失与以非平凡的方式有关，提供了一种可能的替代方法，需要探索通常用于预测纠缠损失的方法。结果为从非平衡热力学的角度从量子方案中理解这种损失提供了一种手段。该框架允许制定策略，以扩大计算时间的最大保真度或纠缠时间。
As has been shown elsewhere, a reasonable model of the loss of entanglement or correlation that occurs in quantum computations is one which assumes that they can effectively be predicted by a framework that presupposes the presence of irreversibilities internal to the system. It is based on the steepest-entropy-ascent principle and is used here to reproduce the behavior of a controlled-PHASE gate in good agreement with experimental data. The results show that the loss of entanglement predicted is related to the irreversibilities in a nontrivial way, providing a possible alternative approach that warrants exploration to that conventionally used to predict the loss of entanglement. The results provide a means for understanding this loss in quantum protocols from a nonequilibrium thermodynamic standpoint. This framework permits the development of strategies for extending either the maximum fidelity of the computation or the entanglement time.
