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…

Causally constrained quantum operator dynamics
Marcell D. Kovács, Christopher J. Turner, Lluís Masanes
Finding analytically tractable model systems for quantum ergodicity breaking in interacting systems remains a theoretical challenge. This paper presents an algebraic theory of robu…

Operator space fragmentation in perturbed Floquet-Clifford circuits
Marcell D. Kovács, Christopher J. Turner, Lluis Masanes +1
Floquet quantum circuits are able to realise a wide range of non-equilibrium quantum states, exhibiting quantum chaos, topological order and localisation. In this work, we investig…
