Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …

Device-independent security is the gold standard for quantum cryptography: not only is
security based entirely on the laws of quantum mechanics, but it holds irrespective of any a …

Abstract We present $\texttt {Cryptomite} $, a Python library of randomness extractor
implementations. The library offers a range of two-source, seeded and deterministic …

Random number generators (RNGs) are notoriously challenging to build and test, especially
for cryptographic applications. While statistical tests cannot definitively guarantee an RNG's …

Secret and perfect randomness is an essential resource in cryptography. Yet, it is not even
clear that such exists. It is well known that the tools of classical computer science do not …

Over the past decades, quantum technology has seen consistent progress, with notable
recent developments in the field of quantum computers. Traditionally, this trend has been …

The field of device-independent (DI) quantum information processing concerns itself with
devising and analysing protocols, such as quantum key distribution, without referring to the …

Multi-source extractors are functions that extract uniform randomness from multiple (weak)
sources of randomness. Quantum multi-source extractors were considered by Kasher and …

We present an end-to-end and practical randomness amplification and privatisation protocol
based on Bell tests. This allows the building of device-independent random number …

Device-independent (DI) quantum cryptography aims at providing secure cryptography with
minimal trust in, or characterisation of, the underlying quantum devices. An essential step in …
