Local contextuality-based self-tests are sufficient for randomness expansion secure against quantum adversaries

Autor: Singh, Jaskaran, Foreman, Cameron, Bharti, Kishor, Cabello, Adán

In quantum cryptography, secure randomness expansion involves using a short private string of random bits to generate a longer one, even in the presence of an adversary who may have access to quantum resources. In this work, we demonstrate that local

Statistical testing of random number generators and their improvement using randomness extraction

Autor: Foreman, Cameron, Yeung, Richie, Curchod, Florian J.

Random number generators (RNGs) are notoriously hard to build and test, especially in a cryptographic setting. Although one cannot conclusively determine the quality of an RNG by testing the statistical properties of its output alone, running numeric

Seedless Extractors for Device-Independent Quantum Cryptography

Autor: Foreman, Cameron, Masanes, Lluis

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 DI protocols is randomness extraction (or privacy amplification) wh

Cryptomite: A versatile and user-friendly library of randomness extractors

Autor: Foreman, Cameron, Yeung, Richie, Edgington, Alec, Curchod, Florian J.

We present Cryptomite, a Python library of randomness extractor implementations. The library offers a range of two-source, seeded and deterministic randomness extractors, together with parameter calculation modules, making it easy to use and suitable

Practical randomness amplification and privatisation with implementations on quantum computers

Autor: Foreman, Cameron, Wright, Sherilyn, Edgington, Alec, Berta, Mario, Curchod, Florian J.

Publikováno v: Quantum 7, 969 (2023)

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 generators which output (near-)perfectly unbiased and private numbers, even i
