In this paper, using the full security framework for continuous variable quantum key distribution (CV-QKD), we provide a composable security proof for the CV-QKD system in a realistic implementation. We take into account equipment losses and contributions from various components of excess noise and evaluate performance against collective and coherent attacks assuming trusted hardware noise. The calculation showed that the system remains operable at channel losses up to 10.2 dB in the presence…

CMRR analysis of instrumentation amplifiers

A set of the simple and practical expressions for the CMRR of instrumentation amplifiers (IAs) based on 2, 3 and 4 opamps is given. These equations take into account not only mismatch of determined

Analysis of the Trusted‐Device Scenario in Continuous‐Variable Quantum Key Distribution

A detailed and comprehensible derivation of the Holevo bound is provided, illustrating the counter‐intuitive fact that an appropriate amount of trusted‐receiver loss and noise can even be beneficial for the key rate.

Long-distance continuous-variable quantum key distribution by controlling excess noise

This work bound the ultimate rates for key and entanglement distribution through a free-space link, where the propagation of quantum systems is generally affected by diffraction, atmospheric extinction, turbulence, pointing errors, and background noise.

Rotation Based Slice Error Correction Protocol for Continuous-variable Quantum Key Distribution and its Implementation with Polar Codes

An improved SEC protocol, named Rotation-based SEC (RSEC), is proposed through performing a random orthogonal rotation on the raw data before quantization, and deducing a new estimator for quantized sequences, which outperforms all previous SEC schemes.

Explicit asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation

An analytical lower bound on the asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation of coherent states is established and shows that relatively small constellation sizes are essentially sufficient to obtain a performance close to a true Gaussian modulation.
