Differential-phase-shift quantum key distribution using coherent light
Differential-phase-shift quantum key distribution based on two nonorthogonal states is described. A weak coherent pulse train is sent from Alice to Bob, in which the phase of each pulse is randomly modulated by $0,p%. Bob measures the differential phase by a one-bit delay circuit. The system has a simple configuration without the need for an interferometer and a bright reference pulse in Alice’...
متن کاملCoherent State Quantum Key Distribution Without Random Basis Switching
The random switching of measurement bases is commonly assumed to be a necessary step of quantum key distribution protocols. In this paper we show that switching is not required for coherent state continuous variable quantum key distribution. We show this via the no-switching protocol which results in higher information rates and a simpler experimental setup. We propose an optimal eavesdropping ...
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 کاملSupplementary 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 ...
