用超导涨落赌博

Gambling with superconducting fluctuations

Marek Foltyn, Maciej Zgirski

摘要:

超导纳米线和约瑟夫森结,当偏置接近超导临界电流时,可以通过热或量子涨落切换到非零电压状态。这个过程被理解为布朗粒子从亚稳态的逃逸。由于这种效应是完全随机的,我们建议使用它来生成随机数。我们提出了获得随机数的协议,并测试其保真度的实验收获的数据。

英文摘要:

Superconducting nanowires and Josephson junctions, when biased close to superconducting critical current, can switch to a non-zero voltage state by thermal or quantum fluctuations. The process is understood as an escape of a Brownian particle from a metastable state. Since this effect is fully stochastic, we propose to use it for generating random numbers. We present protocol for obtaining random numbers and test the experimentally harvested data for their fidelity.
