ABSTRACT
We demonstrated an efficient single-photon frequency upconversion system for the infrared photons at 1.06 μm with ultralow background counts. By pumping the system at a longer wavelength than that of the single-photon signal, the background counts caused by the pump-induced parametric fluorescence in the nonlinear crystal were reduced markedly. We achieved so far the lowest noise of ∼150 /s for a near unity conversion efficiency.

    Einstein, Podolsky, and Rosen pointed out that the quantum-mechanical description of "physical reality" implies an unphysical, instantaneous action between distant measurements. To avoid such an action at a distance, these three concluded that quantum mechanics had to be incomplete. However, its...

    By using the Lewis-Riesenfeld invariant theory, we have studied the dynamical and the geometric phases in the interaction system of multi-atom in micro-cavity with single-mode photon field. We find that the geometric phases in a cycle case have nothing to do with the frequency of the photon...

As stated, it is vital to move the light instead of the scene itself because the photons are lighter and can be moved quickly. In addition,...
