Quantum Beat of Two Single Photons – arXiv Vanity
WebThe interference of two single photons impinging on a beam splitter is measured in a time-resolved manner. Using long photons of different frequencies emitted from an atom-cavity system, a quantum beat with a visibility close to 100% is observed in the correlation between the pho-todetections at the output ports of the beam splitter. WebApr 10, 2024 · We study the interaction of a V-type atom in a cavity with incident single- and two-photon wavepackets and derive an exact formula, valid in all parameter regimes, relating the spectrum of the outgoing wavepackets to the incident one. We present detailed results for several special input pulses, and consider the potential performance of the system as … erp project in django
