论文摘要
我们引入了一个快速且高效的物理可靠的位交换。该设计采用了易于可用且可扩展的约瑟夫森连接微技术，实现了最近引入的动量计算范式。它的纳秒速度和子陆地热力学效率是由动态存储在动量自由度下的动态存储而产生的。因此，在交换过程中，微晶状体分布永远不会接近平衡，并且记忆状态动力学远远超出了随机热力学，该动力学假定具有详细平衡的马尔可夫动力学。该设备实现了一个塑料操作 - 构建可逆通用计算所需的基本操作。广泛的，身体上校准的模拟表明设备性能是稳健的，并且动量计算可以支持热力学效率高，高速，大规模通用计算，从而绕过Landauer的界限。
We introduce a fast and highly-efficient physically-realizable bit swap. Employing readily available and scalable Josephson junction microtechnology, the design implements the recently introduced paradigm of momentum computing. Its nanosecond speeds and sub-Landauer thermodynamic efficiency arise from dynamically storing memory in momentum degrees of freedom. As such, during the swap, the microstate distribution is never near equilibrium and the memory-state dynamics fall far outside of stochastic thermodynamics that assumes detailed-balanced Markovian dynamics. The device implements a bit-swap operation -- a fundamental operation necessary to build reversible universal computing. Extensive, physically-calibrated simulations demonstrate that device performance is robust and that momentum computing can support thermodynamically-efficient, high-speed, large-scale general-purpose computing that circumvents Landauer's bound.
