一种循环冷却算法

A Cyclic Cooling Algorithm

F. Rempp, M. Michel, G. Mahler

摘要:

我们介绍了一种方案来执行冷却算法,首先由Oscar Boykin等人于2002年提出,在同一组qbit上执行任意次数。我们通过在算法中增加一个额外的交换门和一个浴接触来实现这个目标。这样,一个qbit可以重复地被冷却,而无需向系统添加额外的qbit。通过使用乘积Liouville空间来模拟熔池接触,我们计算了系统的密度矩阵后,给定数量的应用程序的算法。

英文摘要:

We introduce a scheme to perform the cooling algorithm, first presented by Oscar Boykin et al. in 2002, for an arbitrary number of times on the same set of qbits. We achieve this goal by adding an additional SWAP-gate and a bath contact to the algorithm. This way one qbit may repeatedly be cooled without adding additional qbits to the system. By using a product Liouville space to model the bath contact we calculate the density matrix of the system after a given number of applications of the algorithm.
