Heralded Generation of Ultrafast Single Photons in Pure Quantum States
Peter J. Mosley, Jeff S. Lundeen, Brian J. Smith +4
We present an experimental demonstration of heralded single photons prepared in pure quantum states from a parametric downconversion source. It is shown that, through controlling t…
Separability of entangled qutrits in noisy channels
Agata Chȩcińska, Krzysztof Wódkiewicz
We present an analysis of noisy atomic channels involving qutrits. We choose a three-level atom with V-configuration to be the qutrit state. Gell-Mann matrices and a generalized Bl…
Interference of Fock states in a single measurement
Andrzej Dragan, Pawel Zin
We study analytically the structure of an arbitrary order correlation function for a pair of Fock states and prove without any approximations that in a single measurement of partic…
Violation of Bell's inequality using classical measurements and non-linear local operations
Magdalena Stobińska, Hyunseok Jeong, Timothy C. Ralph
We find that Bell's inequality can be significantly violated (up to Tsirelson's bound) with two-mode entangled coherent states using only homodyne measurements. This requires Kerr…
