Here we demonstrate generating and storing entanglement in a solid state spin-wave quantum memory with on-demand read out using the process of rephased amplified spontaneous emission (RASE). Amplified spontaneous emission (ASE), resulting from an inv

Space-like separation of entangled quantum states is a central concept in fundamental investigations of quantum mechanics and in quantum communication applications. Optical approaches are ubiquitous in the distribution of entanglement because entangl

We have demonstrated generation, storage, and retrieval of spin-waves in a rare-earth ion-doped crystal via off-resonant spontaneous Raman scattering. Efforts are underway to push this to the single-photon regime.

The production of single photons using rephased amplified spontaneous emission is examined. This process produces single photons on demand with high efficiency by detecting the spontaneous emission from an atomic ensemble, then applying a population-

In this paper we report the first demonstration of ``rephased amplified spontaneous emission'' (RASE) with photon-counting detection. This protocol provides an all-in-one photon-pair source and quantum-memory that has applications as a quantum repeat

Here we propose a solid-state quantum memory that does not require spectral holeburning, instead using strong rephasing pulses like traditional photon echo techniques. The memory uses external broadening fields to reduce the optical depth and so swit

In a solid-state ensemble of rare-earth ions, we have experimentally generated a photon-echo of a spontaneous emission event, a process referred to as rephased amplified spontaneous emission (RASE). An enabling step for this demonstration was to use

We report correlations between multi-photon pulses generated via spontaneous Raman scattering in a rare-earth ion-doped crystal. This is a first step toward implementing a quantum repeater scheme in such a material.

We have characterized a novel photon-echo pulse sequence for a double-Λ-type energy level system where the input and rephasing transitions are different from the applied π pulses. We show that, despite having imperfect π-pulses associated with lar
