DOI: 10.1007/s10773-019-04014-w
Abstract: We propose a scheme of controlled entanglement diversion of a bi-partite entangled coherent state using GHZ type entangled coherent state as a resource. The scheme involves only linear optical devices such as phase shifters, beam… read more here.

Abstract: The scheme of optical imaging using scattering lens can provide a resolution beyond the classical optical diffraction limit with a coherent-state input. Nevertheless, due to the shot noise of the coherent state, the corresponding signal-to-noise… read more here.

DOI: 10.1088/1612-202x/aa772b
Abstract: We propose a theoretical protocol to generate a kind of non-Gaussian state—a Laguerre polynomial excited coherent state (LPECS) by exploiting a two-mode squeezing transformation and a conditional measurement with a coherent state input. Then we… read more here.

DOI: 10.1103/physreva.96.012317
Abstract: A class of Adaptive Decoders (AD's) for coherent-state sequences is studied, including in particular the most common technology for optical-signal processing, e.g., interferometers, coherent displacements and photon-counting detectors. More generally we consider AD's comprising adaptive… read more here.

Abstract: Entangled measurement is a crucial tool in quantum technology. We propose a new entanglement measure of multi-mode detection, which estimates the amount of entanglement that can be created in a measurement. To illustrate the proposed… read more here.

Abstract: We report a directly modulated distributed feedback laser operating in gain-switching mode for preparing the coherent states required for the Gaussian-modulated coherent-state (GMCS) continuous-variable quantum key distribution (CV-QKD) protocol. The proposed single-component quantum transmitter design… read more here.
