Abstract: We investigate two schemes of direct concurrence measurement for two-qubit spin Werner states via the cavity-assisted interaction between single-photon pulses and nitrogen-vacancy centers in diamond. The first scheme requires multiple copies of initial Werner states… read more here.

Abstract: Ideal photonic quantum memories can store arbitrary pulses of light with unit efficiency. This requires operating in the adiabatic regime, where pulses have a duration much longer than the bandwidth of the memory. In the… read more here.

DOI: 10.1103/physrevb.97.205303
Abstract: We study the interplay between charge transport and light-matter interactions in a confined geometry, by considering an open, mesoscopic chain of two-orbital systems resonantly coupled to a single bosonic mode close to its vacuum state.… read more here.
