Entanglement fidelity of quantum memories

Entanglement fidelity of quantum memories

Show other versions (1)

We introduce a figure of merit for a quantum memory which measures the preservation of entanglement between a qubit stored in and retrieved from the memory and an auxiliary qubit. We consider a general quantum memory system consisting of a medium of two level absorbers, with the qubit to be stored e...
