چکیده

We suggest a scheme to reconstruct the covariance matrix of a two-mode state using a single homodyne detector plus a polarizing beam splitter and a polarization rotator. It can be used to fully characterize bipartite Gaussian states and to extract relevant information on generic states.

Full characterization of Gaussian bipartite entangled states by a single homodyne detector.

We present the full experimental reconstruction of Gaussian entangled states generated by a type-II optical parametric oscillator below threshold. Our scheme provides the entire covariance matrix using a single homodyne detector and allows for the complete characterization of bipartite Gaussian states, including the evaluation of purity, entanglement, and nonclassical photon correlations, witho...

A wideband balanced homodyne detector for high speed continuous variable quantum key distribution systems

In Gauissian-modulated coherent-state quantum key distribution, the measurement of quadratures of coherent states is performed by using homodyne detector. However, the existing detectors usually suffer from narrow band. Here we present a method to design a high-speed shot-noise-limited balanced homodyne detector. A 300 MHz bandwidth detector was experimentally tested and the level of shot noise...

Hierarchy of Steering Criteria Based on Moments for All Bipartite Quantum Systems.

Einstein-Podolsky-Rosen steering is a manifestation of quantum correlations exhibited by quantum systems that allows for entanglement certification when one of the subsystems is not characterized. Detecting the steerability of quantum states is essential to assess their suitability for quantum information protocols with partially trusted devices. We provide a hierarchy of sufficient conditions ...

Demonstration 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 ...
