Název v původním jazyce

Experimental tests of energy and time entanglement

Popis výsledku v původním jazyce

Entangled two-photon states are often generated in the process of spontaneous parametric down-conversion. The two photons comprising one pair are tighly correlated in energy and time. The width of these correlations are investigated in interferometric experiments. Unbalanced Mach-Zehnder interferometer in the route of one photon together with a narrow frequency filter in the route of the other one is used to evaluate the widh of the energy correlations. Hong-Ou-Mandel interferometer serves for measurement of the time correlations with the same two-photon source. The measurement results approve the theoretical relation between the time and spectral (energetic) correlations expected for given entangled states. Both the strong energy correlations and narrow time correlations of the detection instants may be exhibited together only by an entangled state.
