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

Random numbers are commonly used in many different fields, ranging from simulations in
fundamental science to security applications. In some critical cases, as Bell's tests and …

An approach to quantum random number generation based on unambiguous quantum state
discrimination is developed. We consider a prepare-and-measure protocol, where two …

We compare the power of quantum and classical physics in terms of randomness
certification from devices which are only partially characterized. We study randomness …

The recent development of perovskite light emitting diodes (PeLEDs) has the potential to
revolutionize the fields of optical communication and lighting devices, due to their simplicity …

Multi-port beam splitters are cornerstone devices for high-dimensional quantum information
tasks, which can outperform the two-dimensional ones. Nonetheless, the fabrication of such …

Quantum random number generators (QRNGs) are able to generate numbers that are
certifiably random, even to an agent who holds some side information. Such systems …

Randomness is a fundamental feature of quantum mechanics, which is an invaluable
resource for both classical and quantum technologies. Practical quantum random-number …

We introduce a scheme for a self-testing quantum random-number generator and
demonstrate it experimentally. Compared to the fully device-independent model, our …

We present a new quantum communication complexity protocol, the promise-quantum
random access code, which allows us to introduce a new measure of unbiasedness for …
