ENTRELAZAMIENTO EN UNA UNIDAD DE MEMORIA CUÁNTICA ÓPTIMA

It is modeled a quantum memory unit as a two qubits interacting with an external bath. The transfer of information from one qubit into the other can be optimally achieved if there exist a good entanglement between them. The two qubits are allocated in a spatial separation d. It is proposed a phenomenological ansatz where their entanglement in presence of noise depends on d. The above opens new possibilities for further operative technologies of quantum memories.
