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

Random numbers are a fundamental resource in science and engineering with important
applications in simulation and cryptography. The inherent randomness at the core of …

Local realism is the worldview in which physical properties of objects exist independently of
measurement and where physical influences cannot travel faster than the speed of light …

Secure communication is crucial in the Internet Age, and quantum mechanics stands poised
to revolutionize cryptography as we know it today. In this Review, we introduce the …

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

Random numbers are central to cryptography and various other tasks. The intrinsic
probabilistic nature of quantum mechanics has allowed us to construct a large number of …

Satellite quantum key distribution (SatQKD) intermediated by a trusted satellite in a low-
Earth orbit to ground stations along the satellite's path allows remote users to connect …

The generation of random numbers is a task of paramount importance in modern science. A
central problem for both classical and quantum randomness generation is to estimate the …

We propose a fully passive linear optical quantum key distribution (QKD) source that
implements both random decoy-state and encoding choices with postselection only, thus …

Random numbers are needed in many areas: cryptography, Monte Carlo computation and
simulation, industrial testing and labeling, hazard games, gambling, etc. Our assumption has …
