量子涨落定理对量子退火机的基准

Quantum fluctuation theorem to benchmark quantum annealers

Bartłomiej Gardas, Sebastian Deffner

摘要:

近期量子硬件有望带来前所未有的计算优势。其发展的关键是表征和最小化计算错误。我们建议使用量子涨落定理来衡量量子退火器的性能。这个多功能的工具提供了简单的方法来确定量子动力学是否是么正的,么正的和绝热的,或者系统是否倾向于热噪声。我们的建议是实验测试的两代的D波机,这说明了波动定理的灵敏度,从理想的退火最小的像差。

英文摘要:

Near term quantum hardware promises unprecedented computational advantage. Crucial in its development is the characterization and minimization of computational errors. We propose the use of the quantum fluctuation theorem to benchmark the performance of quantum annealers. This versatile tool provides simple means to determine whether the quantum dynamics are unital, unitary, and adiabatic, or whether the system is prone to thermal noise. Our proposal is experimentally tested on two generations of the D-Wave machine, which illustrates the sensitivity of the fluctuation theorem to the smallest aberrations from ideal annealing.
