Quantum systems modelling and simulation activity is a challenging research area. Several models and applications were proposed in the past with different approaches. Special purposes models based on cellular automata (CA) paradigm were studied as the classical CA present limits in quantum system characterisation. In this Letter we deal with a CA based approach for studying and characterizing mesoscopic quantum systems, showing that, when adopting particular system conditions, the corresponding model is simple by means of such a computational approach. We focus on fully frustrated linear Josephson junction arrays with non-trivial geometry, which develop topological order allowing for the implementation of protected qubits, a first step toward the realization of an ideal solid state quantum computer.

Abstract
Quantum systems modelling and simulation activity is a challenging research area. Several models and applications were proposed in the past with different approaches. Special purposes models based on cellular automata (CA) paradigm were studied as the classical CA present limits in quantum system characterisation. In this Letter we deal with a CA based approach for studying and characterizing mesoscopic quantum systems, showing that, when adopting particular system conditions, the corresponding model is simple by means of such a computational approach. We focus on fully frustrated linear Josephson junction arrays with non-trivial geometry, which develop topological order allowing for the implementation of protected qubits, a first step toward the realization of an ideal solid state quantum computer.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
