Tight bound on coherent states quantum key distribution with heterodyne detection

, 2007
We propose a new upper bound for the eavesdropper's information in the direct and reverse reconciliated coherent states quantum key distribution protocols with heterodyne detection.

Performance Analysis of a Threshold-Based Parallel Multiple Beam Selection Scheme for WDM FSO Systems

IEEE Access, 2018
In this paper, we statistically analyze the performance of a threshold-based parallel multiple beam selection scheme for a free-space optical-based system with wavelength division multiplexing in cases where a pointing error has occurred under ...

Quantum Hacking on Continuous-Variable Quantum Key Distribution System using a Wavelength Attack

, 2013
The security proofs of continuous-variable quantum key distribution are based on the assumptions that the eavesdropper can neither act on the local oscillator nor control Bob's beam splitter.

Coherent spectroscopies on ultrashort time and length scales

EPJ Web of Conferences, 2013
Three spectroscopic techniques are presented that provide simultaneous spatial and temporal resolution: modified confocal microscopy with heterodyne detection, space-time-resolved spectroscopy using coherent control concepts, and coherent two-dimensional

Heterodyne Detection of Electronic Optical Activity in Time-Domain: Single-Shot Chiroptical Spectrometry

EPJ Web of Conferences, 2013
We demonstrate that an ultimately sensitive chiroptical measurement at single femtosecond pulse level can be achieved using heterodyne-detection techniques. These methods will be of use to observe molecular chirality changes in ultrafast time domain.

Applying Gaussian quantum discord to quantum key distribution

, 2014
In this paper, we theoretically prove that the Gaussian quantum discord state of optical field can be used to complete continuous variable (CV) quantum key distribution (QKD). The calculation shows that secret key can be distilled with a Gaussian quantum
