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].

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].File in questo prodotto:
