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

Self-testing is a method to infer the underlying physics of a quantum experiment in a black
box scenario. As such it represents the strongest form of certification for quantum systems. In …

Semidefinite programs are convex optimization problems involving a linear objective
function and a domain of positive-semidefinite matrices. Over the past two decades, they …

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

The concept of randomness plays an important part in many disciplines. On the one hand,
the question of whether random processes exist is fundamental for our understanding of …

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 …

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 …

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