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…

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…

Resource theories of multi-time processes: A window into quantum non-Markovianity
Graeme D. Berk, Andrew J. P. Garner, Benjamin Yadin +2
We investigate the conditions under which an uncontrollable background processes may be harnessed by an agent to perform a task that would otherwise be impossible within their oper…
