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

چکیده
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. © 2006 Elsevier B.V.

Introducing Reversibility in a High Level JJL Qubit Model According to CAN2 Paradigm
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 relev...
متن کاملAddressing Reversibility in Quantum Devices by a Hybrid CA Approach: the JJL Case
Reversibility is a concept widely studied in several research fields. Several contributions have been provided in physics and computer science. Reversible computation is characterized by means of invertible properties [1]. Reversibility is studied in computer science also in order to design less dissipative computers. The evolution of quantum systems is described by the time evolution operator ...
متن کاملA Basic Qualitative CA Based Model of a Frustrated Linear Josephson Junction Array (JJA)
Quantum Systems modeling 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 characterization. In this paper we derive a basic qualitative model, according to the Cellular Autom...
متن کاملRole of theology in the acceptance of autistic children by their mothers: An original qualitative study
Background and Purpose: One of the factors influencing the acceptance of autistic children by their mothers is the mothers’ attitude towards God. The present study aimed to investigate the role of mothers’ theological viewpoints and attitudes towards God on accepting the autistic child. Materials and Methods: This study was qualitative and an unstructured interview was conducted to collect inf...
متن کاملThermal negativity in a two qubit XXX and XX spin chain model in an external magnetic field
In this paper we studied the thermal negativity in a two-qubit XX spin ½ chain model and XXX spin1/2 chain model(isotropic Heisenberg model)spin-1/2 chain subjected to an external magnetic field inz direction. We calculate analytical relation for the thermal negativity for two qubit XX and XXX spinchain models in the external magnetic field. Effects of the magnetic field and temperature on then...
