How much randomness in a quantum process can be explained using memory?
Derek D. C. Chang, Graeme D. Berk, Mile Gu
For a stochastic process describing observations of a dynamical system, complexity science provides systematic methods to decompose the information produced into true irreducible r…
Quantum Circuit Fragments and Link Products in Continuous Variables
Amalina Lai, Graeme D. Berk, Minjeong Song +1
Quantum circuits are often drawn as complete processes, with fixed inputs and outputs. In many quantum-information tasks, however, the natural object is only a fragment of such a c…
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…
Extracting Quantum Dynamical Resources: Consumption of Non-Markovianity for Noise Reduction
Graeme D. Berk, Simon Milz, Felix A. Pollock +1
Noise is possibly the most formidable challenge for quantum technologies. As such, a great deal of effort is dedicated to developing methods for noise reduction. One remarkable ach…
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…
