Towards reversibility in a JJL qubit qualitative model by means of CAN2 paradigm

Reversibility is a concept widely studied in physics and computer science. Quantum systems evolution is described by the time evolution operator U, which is unitary and then invertible. Likewise, reversible computation is characterized by means of invertible properties. Reversible/invertible cellular automata (CA) are one of the most relevant reversible computational models. Here we introduce a model for a Josephson junction ladder (JJL) device which turns out to be reversible: it is based on a hybrid cellular automata network (CAN), the CAN2 one.
