Enhancing image contrast using coherent states and photon number resolving detectors.

چکیده
We experimentally map the transverse profile of diffractionlimited beams using photon-number-resolving detectors.We observe strong compression of diffracted beam profiles for high detected photon number. This effect leads to higher contrast than a conventional irradiance profile between two Airy disk-beams separated by the Rayleigh criterion.

Phase-reference monitoring in coherent-state discrimination assisted by a photon-number resolving detector
Phase estimation represents a crucial challenge in many fields of Physics, ranging from Quantum Metrology to Quantum Information Processing. This task is usually pursued by means of interferometric schemes, in which the choice of the input states and of the detection apparatus is aimed at minimizing the uncertainty in the estimation of the relative phase between the inputs. State discrimination...
متن کاملDemonstration of coherent-state discrimination using a displacement-controlled photon-number-resolving detector.
We experimentally demonstrate a new measurement scheme for the discrimination of two coherent states. The measurement scheme is based on a displacement operation followed by a photon-number-resolving detector, and we show that it outperforms the standard homodyne detector which we, in addition, prove to be optimal within all Gaussian operations including conditional dynamics. We also show that ...
متن کاملSampling of the Wigner function adapted to time-multiplexed detection of photon statistics
We investigate the capabilities of loss-tolerant quantum state characterisation based on photon-number resolving detectors. Our emphasis lies on constructing the Wigner function of non-Gaussian Fock states with highly non-classical negative values around the origin of the phase space. We employ the idea of sampling the Wigner function point by point via photon parity measurements instead of usi...

In this paper, by using the nonlinear coherent states on a sphere, we introduce superposition of the aforementioned coherent states. Then, we consider quantum optical properties of these new superposed states and compare these properties with the corresponding properties of the nonlinear coherent states on the sphere. Specifically, we investigate their characteristics function, photon-number d...
متن کاملTight bound on coherent-state-based entanglement generation over lossy channels
The first stage of the hybrid quantum repeaters is entanglement generation based on transmission of pulses in coherent states over a lossy channel. Protocols to make entanglement with only one type of error are favorable for rendering subsequent entanglement distillation efficient. Here we provide the tight upper bound on performances of these protocols that is determined only by the channel lo...
