Single-quadrature continuous-variable quantum key distribution
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. Here, we propose and experimentally test a largel...
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...
متن کاملHigh-speed free-space optical continuous-variable quantum key distribution enabled by three-dimensional multiplexing.
A high-speed four-state continuous-variable quantum key distribution (CV-QKD) system, enabled by wavelength-division multiplexing, polarization multiplexing, and orbital angular momentum (OAM) multiplexing, is studied in the presence of atmospheric turbulence. The atmospheric turbulence channel is emulated by two spatial light modulators (SLMs) on which two randomly generated azimuthal phase pa...
متن کاملSecurity Thresholds of Multicarrier Continuous-Variable Quantum Key Distribution
We prove the secret key rate formulas and derive security threshold parameters of multi-carrier continuous-variable quantum key distribution (CVQKD). In a multicarrierCVQKD scenario, the Gaussian input quantum states of the legal parties are granulatedinto Gaussian subcarrier CVs (continuous-variables). The multicarrier communicationformulates Gaussian sub-channels from the ...
متن کاملSubcarrier Domain of Multicarrier Continuous-Variable Quantum Key Distribution
We propose the subcarrier domain of multicarrier continuous-variable (CV) quantum key distribution (QKD). In a multicarrier CVQKD scheme, the information is granulated into Gaussian subcarrier CVs and the physical Gaussian link is divided into Gaussian subchannels. The sub-channels are dedicated for the conveying of the subcarrier CVs. The angular domain utilizes the phase-space angles of the G...
