物理和编码量子比特的高效通用泄漏消除

Efficient Universal Leakage Elimination for Physical and Encoded Qubits

L. -A. Wu, M. S. Byrd, D. A. Lidar

摘要:

退相干引起的泄漏错误可以将物理或编码的量子位耦合到其他级别,从而潜在地损坏量子位。因此,它们在量子计算中可能非常有害,需要特别注意。在这里,我们提出了一个通用的方法,通过使用简单的去耦和再耦合脉冲序列来消除这种误差。所提出的门在实验上可用于各种有前途的量子计算方案。

英文摘要:

Decoherence-induced leakage errors can couple a physical or encoded qubit to other levels, thus potentially damaging the qubit. They can therefore be very detrimental in quantum computation and require special attention. Here we present a general method for removing such errors by using simple decoupling and recoupling pulse sequences. The proposed gates are experimentally accessible in a variety of promising quantum computing proposals.
