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.
Se modela una unidad de memoria cuántica como dos qubits interactuando con un baño externo. La transferencia de información de un qubit a otro puede lograrse de manera óptima si existe un buen entrelazamiento entre ellos. Los dos qubits están ubicados a una separación espacial d. Se propone un ansatz fenomenológico en el que su entrelazamiento en presencia de ruido depende de d. Lo anterior abre nuevas posibilidades para futuras tecnologías operativas de memorias cuánticas.
