离子阱量子计算机中量子位耦合故障的检测

Detecting Qubit-coupling Faults in Ion-trap Quantum Computers

摘要:

离子阱量子计算机提供了大量可能的量子位耦合,每一个都需要单独的校准,并且可能被错误配置。为了提高占空比的离子阱,我们开发了一种策略,诊断个人的失调耦合,只使用对数许多测试。这种策略在商业离子阱量子计算机上得到了验证,在那里我们说明了故障量子门的调试过程。我们的方法提供了一个可扩展的途径,在更大规模的离子阱量子计算机上进行故障检测,并通过高达32个量子比特的模拟得到证实。

英文摘要:

Ion-trap quantum computers offer a large number of possible qubit couplings, each of which requires individual calibration and can be misconfigured. To enhance the duty cycle of an ion trap, we develop a strategy that diagnoses individual miscalibrated couplings using only log-many tests. This strategy is validated on a commercial ion-trap quantum computer, where we illustrate the process of debugging faulty quantum gates. Our methodology provides a scalable pathway towards fault detections on a larger scale ion-trap quantum computers, confirmed by simulations up to 32 qubits.
