Temporal Kirkwood-Dirac Quasiprobability Distribution and Unification of Temporal State Formalisms through Temporal Bloch Tomography
Zhian Jia, Kavan Modi, Dagomir Kaszlikowski
Temporal quantum states generalize the multipartite density operator formalism to the time domain, enabling a unified treatment of quantum systems with both timelike and spacelike…
Quantifiers of Noise Reducibility Under Restricted Control
Graeme D. Berk, Kavan Modi, Simon Milz
The correlation structure of multitime quantum processes - succinctly described by quantum combs - is an important resource for many quantum information protocols and control tasks…
What can unitary sequences tell us about multi-time physics?
Gregory A. L. White, Felix A. Pollock, Lloyd C. L. Hollenberg +2
Multi-time quantum processes are endowed with the same richness as multipartite states, including temporal entanglement and exotic causal structures. However, experimentally probin…
Monotones in Resource Theories for Dynamical Decoupling
Graeme D. Berk, Simon Milz, Kavan Modi
In arXiv:2110.02613, we presented a generalised dynamical resource theory framework that enabled noise reduction techniques including dynamical decoupling (DD) to be studied. While…
Higher-Order Quantum Operations
Philip Taranto, Simon Milz, Mio Murao +2
An operational description of quantum phenomena concerns developing models that describe experimentally observed behaviour. $\textit{Higher-order quantum operations}\unicode{x2014}…
