Abstract

Magnetic skyrmions are nanoscale whirls of magnetism that can be propagated with electrical currents. The repulsion between skyrmions inspires their use for reversible computing based on the elastic billiard ball collisions proposed for conservative logic in 1982. In this letter, we evaluate the logical and physical reversibility of this skyrmion logic paradigm, as well as the limitations that must be addressed before dissipation-free computation can be realized.

保守Skyrmion逻辑的逻辑可逆性和物理可逆性

磁性skyrmions是纳米级的磁性漩涡，可以通过电流传播。skyrmions之间的排斥激发了它们在1982年为保守逻辑提出的弹性台球碰撞的基础上用于可逆计算。在这封信中，我们评估了这种skyrmion逻辑范式的逻辑和物理可逆性，以及在实现无耗散计算之前必须解决的限制。
