Symmetries of quantum evolutions

no code implementations13 Jan 2021 Giulio Chiribella, Erik Aurell, Karol Życzkowski

Our no-go theorem implies that any time symmetric formulation of quantum theory must either restrict the set of the allowed evolutions, or modify the operational interpretation of quantum states and processes.

Efficient verification of continuous-variable quantum states and devices without assuming identical and independent operations

no code implementations7 Dec 2020 Ya-Dong Wu, Ge Bai, Giulio Chiribella, Nana Liu

To successfully demonstrate these protocols, an essential step is the certification of multimode continuous-variable quantum states and quantum devices.

Quantum operations with indefinite time direction

no code implementations7 Dec 2020 Giulio Chiribella, Zixuan Liu

A fundamental question is whether it is in principle possible to probe a quantum dynamics in the backward direction, or in more general combinations of the forward and the backward direction.

Proceedings of the 15th International Conference on Quantum Physics and Logic

no code implementations28 Jan 2019 Peter Selinger, Giulio Chiribella

Quantum Physics and Logic is an annual conference that brings together researchers working on mathematical foundations of quantum physics, quantum computing, and related areas, with a focus on structural perspectives and the use of logical tools, ordered algebraic and category-theoretic structures, formal languages, semantical methods, and other computer science techniques applied to the study of physical behaviour in general.
