Supplementary information for " High - rate quantum key distribution using Gaussian - modulated coherent states "
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 کاملQuantum key distribution using polarized coherent states
We discuss a continuous variables method of quantum key distribution employing strongly polarized coherent states of light. The key encoding is performed using the variables known as Stokes parameters, rather than the field quadratures. Their quantum counterpart, the Stokes operatorsˆSi (i=1,2,3), constitute a set of non-commuting operators, being the precision of simultaneous measurements of a...
متن کاملExperimental 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...
متن کاملQuantum key distribution using bright polarized coherent states
We propose a novel protocol for quantum key distribution based on the quantum polarization properties of coherent states. The key elements are encoded either in the component amplitude difference or in the phase difference of Gaussian-modulated strong coherent fields. The quantum counterpart (Stokes operators) of the classical parameters which represent the preponderance of xlinear polarization...
متن کاملQuantum Key Distribution using Continuous-variable non-Gaussian States
In this work we present a quantum key distribution protocol using continuous-variable nonGaussian states, homodyne detection and post-selection. The employed signal states are the Photon Added then Subtracted Coherent States (PASCS) in which one photon is added and subsequently one photon is subtracted. We analyze the performance of our protocol, compared to a coherent state based protocol, for...
