论文摘要

保护量子的连贯性是为了建立一个能够以高度忠诚度操纵,存储和读取量子信息的实用量子计算机的重要任务。最近,有人提出通过强脉冲来增加量子的运行时间,以实现与环境的动力脱钩。我们提出并演示了一种基于浮标模式的简单且高效的替代脉冲协议,这增加了许多具有不同自旋汉密尔顿和环境的材料中的破坏时间。我们演示了制度$ t_2 \ of t_1 $,因此为旋转量子台和旋转合奏提供了一条路线,用于量子信息处理和存储。

The protection of qubit coherence is an essential task in order to build a practical quantum computer able to manipulate, store and read quantum information with a high degree of fidelity. Recently, it has been proposed to increase the operation time of a qubit by means of strong pulses to achieve a dynamical decoupling of the qubit from its environment. We propose and demonstrate a simple and highly efficient alternative pulse protocol based on Floquet modes, which increases the decoherence time in a number of materials with different spin Hamiltonians and environments. We demonstrate the regime $T_2\approx T_1$, thus providing a route for spin qubits and spin ensembles to be used in quantum information processing and storage.
