  We perform a theoretical investigation into how a two-mode squeezed vacuum
state, that has undergone photon loss, can be stored and purified using
noiseless amplification with a collection of solid-state qubits. The proposed
method may be used to probabilistically increase the entanglement between the
two parties sharing the state. The proposed amplification step is similar in
structure to a set of quantum scissors. However, in this work the amplification
step is realized by a state transfer from an optical mode to a set of
solid-state qubits, which act as a quantum memory. We explore two different
applications, the generation of entangled many-qubit registers, and the
construction of quantum repeaters for long-distance quantum key distribution.
