Photon-pair source with controllable delay based on shaped inhomogeneous broadening of rare-earth-metal-doped solids
Spontaneous Raman emission in atomic gases provides an attractive source of photon pairs with a controllable delay. We show how this technique can be implemented in solid state systems by appropriately shaping the inhomogeneous broadening. Our proposal is eminently feasible with current technology and provides a realistic solution to entangle …
