Experimental study on Gaussian-modulated coherent states quantum key distribution over standard telecom fiber
In this paper, we present a fully fiber-based one-way Quantum Key Distribution (QKD) system implementing the Gaussian-Modulated Coherent States (GMCS) protocol. The system employs a double Mach-Zehnder Interferometer (MZI) configuration in which the weak quantum signal and the strong Local Oscillator (LO) go through the same fiber between Alice and Bob, and are separated into two paths inside B...

High Speed Homodyne Detector for Gaussian-Modulated Coherent-State Quantum Key Distribution Yuemeng Chi Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2009 We developed a high speed homodyne detector in the telecommunication wavelength region for a Gaussian-modulated coherent-state quantum key distribution experiment. We are able to ac...
متن کاملExperimental Decoy State Quantum Key Distribution Over 15km
Decoy state protocols have recently been proposed as an innovative approach to improve dramatically the performance of quantum key distribution systems. Here, we present the first experimental demonstration of decoy state quantum key distribution, over 15km of Telecom fibers.

The source consists of a CW laser diode (SDL 5412) at 780nm associated with an acousto-optic modulator, used to chop pulses with a duration 120ns (full width at halfmaximum), at a repetition rate 800kHz. To reduce the excess noise, a grating-extended external cavity is used, and the beam is spatially filtered using a single mode fiber. Light pulses are then split onto a beam-splitter, one beam ...
متن کاملCoherent state quantum key distribution based on entanglement sudden death
A method for quantum key distribution (QKD) using entangled coherent states is discussed which is designed to provide key distribution rates and transmission distances surpassing those of traditional entangled photon pair QKD by exploiting entanglement sudden death. The method uses entangled electromagnetic signal states of ‘macroscopic’ average photon numbers rather than single photon or entan...
