Quantum key distribution provides secure keys with information-theoretic security ensured
by the principle of quantum mechanics. The continuous-variable version of quantum key …

Realizing a large-scale quantum computer requires hardware platforms that can
simultaneously achieve universality, scalability, and fault tolerance. As a viable pathway to …

Quantum cryptography founded on the laws of physics could revolutionize the way in which
communication information is protected. Significant progresses in long-distance quantum …

Quantum physics can be exploited to generate true random numbers, which have important
roles in many applications, especially in cryptography. Genuine randomness from the …

Quantum cryptography achieves a formidable task—the remote distribution of secret keys by
exploiting the fundamental laws of physics. Quantum cryptography is now headed towards …

Continuous-variable quantum key distribution (CV-QKD) protocols based on coherent
detection have been studied extensively in both theory and experiment. In all the existing …

Quantum information and communication technology will lead us to the new era of ultra‐fast
and absolute‐secure networks. With the emergence of quantum supremacy on the horizon …

We report a 100-MHz continuous-variable quantum key distribution (CV-QKD) experiment
over a 25-km fiber channel without sending a local oscillator (LO). We use a “locally” …

Establishing an information-theoretic secret key between two parties using a quantum key
distribution (QKD) system is only possible when an accurate characterization of the quantum …

We report the first continuous-variable quantum key distribution (CVQKD) experiment to
enable the creation of 1 Mbps secure key rate over 25 km standard telecom fiber in a coarse …
