General Entropic Constraints on Calderbank-Shor-Steane Codes within Magic Distillation Protocols

Autor: Rhea Alexander, Si Gvirtz-Chen, Nikolaos Koukoulekidis, David Jennings

Publikováno v: PRX Quantum, Vol 4, Iss 2, p 020359 (2023)

Magic states are fundamental building blocks on the road to fault-tolerant quantum computing. Calderbank-Shor-Steane (CSS) codes play a crucial role in the construction of magic distillation protocols. Previous work has cast quantum computing with ma

Infinitesimal reference frames suffice to determine the asymmetry properties of a quantum system

Autor: Rhea Alexander, Si Gvirtz-Chen, David Jennings

Publikováno v: New Journal of Physics, Vol 24, Iss 5, p 053023 (2022)

Symmetry principles are fundamental in physics, and while they are well understood within Lagrangian mechanics, their impact on quantum channels has a range of open questions. The theory of asymmetry grew out of information-theoretic work on entangle

The geometry of passivity for quantum systems and a novel elementary derivation of the Gibbs state

Autor: Nikolaos Koukoulekidis, Rhea Alexander, Thomas Hebdige, David Jennings

Publikováno v: Quantum, Vol 5, p 411 (2021)

Passivity is a fundamental concept that constitutes a necessary condition for any quantum system to attain thermodynamic equilibrium, and for a notion of temperature to emerge. While extensive work has been done that exploits this, the transition fro
