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

The security of quantum key distribution (QKD) usually relies on that the users' devices are
well characterized according to the security models made in the security proofs. In contrast …

Device-independent quantum key distribution (DI-QKD) is often seen as the ultimate key
exchange protocol in terms of security, as it can be performed securely with uncharacterised …

Device-independent quantum key distribution (DIQKD) is the art of using untrusted devices
to distribute secret keys in an insecure network. It thus represents the ultimate form of …

Alice and Bob each have half of a pair of entangled qubits. Bob measures his half and then
passes his qubit to a second Bob who measures again and so on. The goal is to maximize …

Device-independent (DI) quantum secret sharing (QSS) can relax the security assumptions
about the devices' internal workings and provide QSS the highest level of security in theory …

Entanglement in bipartite systems has been applied to generate secure random numbers,
which are playing an important role in cryptography or scientific numerical simulations. Here …

Random numbers are a basic ingredient of simulation algorithms and cryptography, and
play a significant part in computer simulation and information processing. One prominent …

The recent development of perovskite light emitting diodes (PeLEDs) has the potential to
