Simple security proofs for continuous variable quantum key distribution with intensity fluctuating sources [PDF]
npj Quantum Information, 2021 Despite tremendous theoretical and experimental progress in continuous variable (CV) quantum key distribution (QKD), the security has not been rigorously established for most current continuous variable quantum key distribution systems that have ...

Hybrid Continuous-discrete Variable Quantum Key Distribution
Guangtongxin yanjiu, 2023 As one of the main applications of quantum cryptography, Quantum Key Distribution (QKD) is a promising secure key transmission method. Compared with traditional communication methods, QKD protocols based on the basic principles of quantum mechanics have ...

CONTINUOUS VARIABLE QUANTUM KEY DISTRIBUTION [PDF]
, 2022 Continuous-Variable Quantum Key Distribution is an alternative to the usual discrete variable quantum key distribution schemes, such as BB84, based on quantum states of light. Optical quantum states are defined in an infinite dimensional Hilbert space hence the "continuous" prefix.

Continuous-Variable Quantum Key Distribution [PDF]
, 2007 Quantum key distribution is a technique in which secret key bits are encoded into quantum states, which are transmitted over a quantum channel (e.g., an optical link) so that the security is guaranteed by the laws of quantum physics. Most experimental realizations to date have relied on discrete protocols, involving ideally single-photons states (or ...

Single-quadrature continuous-variable quantum key distribution [PDF]
Quantum Information and Computation, 2016 Most continuous-variable quantum key distribution schemes are based on the Gaussian modulation of coherent states followed by continuous quadrature detection using homodyne detectors. In all previous schemes, the Gaussian modulation has been carried out in conjugate quadratures thus requiring two independent modulators for their implementations.

Long-Distance Continuous-Variable Quantum Key Distribution With Quantum Scissors [PDF]
IEEE Journal of Selected Topics in Quantum Electronics, 2020 The use of quantum scissors, as candidates for non-deterministic amplifiers, in continuous-variable quantum key distribution systems is investigated. Such devices rely on single-photon sources for their operation and as such, they do not necessarily preserve the Guassianity of the channel. Using exact analytical modeling for system components, we bound

Noiseless Linear Amplifiers in Entanglement-Based Continuous-Variable Quantum Key Distribution [PDF]
Entropy, 2015 We propose a method to improve the performance of two entanglement-based continuous-variable quantum key distribution protocols using noiseless linear amplifiers. The two entanglement-based schemes consist of an entanglement distribution protocol with an

Polarization-agnostic continuous-variable quantum key distribution
Physical Review AWe present a polarization agnostic encoding method for continuous-variable quantum key distribution in which the receiver measures valid Gaussian modulated coherent state quadratures even when the signal polarization is “scrambled” during transmission.
