Abstract

We report the storage of microwave pulses at the single-photon level in a spin-ensemble memory consisting of 1010 nitrogen-vacancy centers in a diamond crystal coupled to a superconducting LC resonator. The energy of the signal, retrieved 100μs later by spin-echo techniques, reaches 0.3% of the energy absorbed by the spins. This 0.3% storage efficiency is quantitatively accounted for by simulations. This figure of merit is sufficient to envision first implementations of a quantum memory for superconducting qubits.
