To estimate the risk of hemorrhagic complications associated with 25-gauge pars plana vitrectomy (PPV) when warfarin (Coumadin; Bristol-Myers Squibb, New York, NY) or clopidogrel (Plavix; Bristol-Myers Squibb) are continued throughout the surgical period, as compared with a control group.A single-center, retrospective, cohort study of 289 consecutive patients receiving either warfarin therapy or clopidogrel...
Polarisation squeezing in optical fibres is an efficient means of producing highly squeezed light. Because the experiments operate in a very nonclassical regime, the results are very sensitive to additional nonlinear and thermal effects in the fibre. To quantitatively characterise such experiments, we perform first-principles, quantum dynamical simulations of intense, ultrashort pulses in a fibre,...
We report on the generation of polarization squeezed states employing intense, ultrashort light pulses by a single pass method in photonic crystal fibers. We investigated the squeezing behavior near the zero-dispersion wavelength and in the anomalous dispersion regime by using two distinct fibers.
Continuous variable polarization states have attracted much attention due to their apparent applicability to quantum information networks. Polarization entanglement was presented by transformation of the well-known quadrature entanglement onto the polarization basis. The inseparability criteria as well as the EPR paradox criteria for Stokes operators were also demonstrated. In this paper the generation...
The first quantum reconstruction of an intense Kerr squeezed state is reported. Taking into account the algebraic properties of the Stokes operators, the Wigner function describing a polarization squeezed state can also be fully reconstructed.
We report on the excellent agreement of a first-principles, quantum dynamical simulation with the experimentally measured results of a fiber squeezer using intense, ultra-short laser pulses.
We report on the first experimental distillation of an intense squeezed state from a non-Gaussian mixture of polarization squeezed states. Conditioning the signal on a tap measurement, we observe probabilistic recovery of the squeezing.
