Abstract

Reversibility is a concept widely studied in physics as well as in computer science Reversible computation is characterized by means of invertible properties [1] Quantum systems evolution is described by the time evolution operator U, which is unitary and invertible; therefore such systems can implement reversibility Reversible/invertible Cellular Automata (CA) [1] are one of the most relevant reversible computational models Here we introduce a model for a Josephson junction ladder (JJL) device addressing reversibility: it is based on a hybrid Cellular Automata Network (CAN), the CAN2 one[2][3][4].
