High-rate and computationally-efficient seedless extractors for device-independent quantum cryptography
Simone Lin, Cameron Foreman, Lluis Masanes
Device-independent (DI) quantum cryptography provides secure cryptography with minimal trust in, or characterisation of, the used quantum devices. An essential component of DI prot…

Seedless extractors for device-independent quantum cryptography
Cameron Foreman, Lluis Masanes
Device-independent (DI) quantum cryptography aims at providing secure cryptography with minimal trust in, or characterisation of, the underlying quantum devices. A key step in DI p…

Local contextuality-based self-tests are sufficient for randomness expansion secure against quantum adversaries
Jaskaran Singh, Cameron Foreman, Kishor Bharti +1
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 hav…
