Journal ArticleDOI
Long-Distance Continuous-Variable Quantum Key Distribution with Entangled States
TL;DR: The authors succeed in distributing Einstein-Podolsky-Rosen entangled states over a 50-km standard fiber with negligible excess noise, and further demonstrate CV-QKD in a high-noise environment with performance superior to that of the optimized coherent-state protocol.
Journal ArticleDOI
Imperfect state preparation in continuous-variable quantum key distribution
TL;DR: To ensure an accurate estimate of the quantum channel parameters and achieve a reliable quantum key distribution, this work proposes and demonstrates two effective schemes to calibrate the working parameters of the modulators.
Journal ArticleDOI
Experimental demonstration of continuous-variable measurement-device-independent quantum key distribution over optical fiber
TL;DR: In this article , a continuous-variable (CV) Bell-state measurement (BSM) of two remote independent quantum states over optical fiber has been demonstrated, and the achieved secret key rates are 0.43 (0.19) bits per pulse over a 5-km (10-km) optical fiber.
Journal ArticleDOI
Impact of Four-Wave-Mixing Noise from Dense Wavelength-Division-Multiplexing Systems on Entangled-State Continuous-Variable Quantum key Distribution
Shanna Du,Yan Tian,Yongmin Li +2 more
TL;DR: In this article, the authors investigated the influence of cross-phase modulation noise between the carrier of the quantum signal and classical data channels on the QKD performance and proposed an unequal channel spacing technique to suppress the effect of the four-wave mixing noise.
Journal ArticleDOI
High-speed time-domain balanced homodyne detector for nanosecond optical field applications
TL;DR: In this article, a high-speed time-domain shot-noise-limited balanced homodyne detector was proposed for the detection of the quantum states of nanosecond pulsed optical fields.
