Continuous-variable quantum cryptography has emerged as a significant branch of quantum cryptography, with continuous-variable quantum key distribution (CVQKD) at its core. However, compared to ...

Scientists at the University of York's Centre for Quantum Technology have discovered new evidence to support the development of scalable and secure high rate quantum networks. Earlier research with ...

Figure 1: Schematic of a quantum key distribution system. The transmitter (Alice) and receiver (Bob) generate composable keys by transmitting quantum states over an insecure quantum channel, ...

Innovate UK’s £1.5 million MARCONI project aims to demo quantum key distribution (QKD) via high-fidelity, modular, and scalable receiver modules. Innovate UK’s £1.5 million MARCONI project aims to ...

Continuous-variable quantum key distribution (CV-QKD) utilises the continuous degrees of freedom of light—typically the amplitude and phase quadratures of coherent states—to establish ...

The MARCONI project is set to transform the landscape of quantum key distribution (QKD) by developing and demonstrating high-fidelity, modular, and scalable receiver modules. Credit: MARCONI project ...
