Exact distinguishability between real-valued and complex-valued Haar random quantum states
Tristan Nemoz, Romain Alléaume, Peter Brown
Haar random states are fundamental objects in quantum information theory and quantum computing. We study the density matrix resulting from sampling copies of a -dimensional…

How much secure randomness is in a quantum state?
Kriss Gutierrez Anco, Tristan Nemoz, Peter Brown
How much cryptographically-secure randomness can be extracted from a quantum state? This fundamental question probes the absolute limits of quantum random number generation (QRNG)…
