Topic: cryptographic protocols

Work with the PHIQUS team on distributed quantum computation, quantum correlations and nonlocality, or cryptographic protocols. Mathematical approaches include noncommutative polynomial optimisation and operator algebras. Projects are tailored to the researcher’s expertise and connect with European quantum-information collaborations. The page describes opportunities lasting one to three years, while its formal contract field specifies two years; applicants should confirm the duration for their appointment.

Thomas Schuster uses quantum-information dynamics to study complexity in increasingly coherent experimental systems. A classical polynomial-time algorithm for circuits with uncorrected noise establishes limits on their possible quantum advantage. A second result shows that universal random-matrix behaviour can emerge exponentially faster than previously expected in local circuits and time evolution, with implications for benchmarking, cryptographic protocols and fundamental physics.
