Influence of pump coherence on the quantum properties of spontaneous parametric down-conversion

2018 · Physica Scripta

Abstract The correlation properties of the pump field in spontaneous parametric down-conversion are crucial in determining the degree of entanglement of generated signal and idler photons. We find theoretically that continuous-variable entanglement of the transverse …

The phase sensitivity of a fully quantum three-mode nonlinear interferometer

2018 · New Journal of Physics

We study a nonlinear interferometer consisting of two consecutive parametric amplifiers, where all three optical fields (pump, signal and idler) are treated quantum mechanically, allowing for pump depletion and other quantum phenomena. The interaction of …
