Equilibration of Multitime Quantum Processes in Finite Time Intervals
Neil Dowling, Pedro Figueroa-Romero, Felix A. Pollock +2
A generic non-integrable (unitary) out-of-equilibrium quantum process, when interrogated across many times, is shown to yield the same statistics as an (non-unitary) equilibrated p…
Reduced Dynamics of Full Counting Statistics
Felix A. Pollock, Emanuel Gull, K. Modi +1
We present a theory of modified reduced dynamics in the presence of counting fields. Reduced dynamics techniques are useful for describing open quantum systems at long emergent tim…
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…
Relaxation of Multitime Statistics in Quantum Systems
Neil Dowling, Pedro Figueroa-Romero, Felix A. Pollock +2
Equilibrium statistical mechanics provides powerful tools to understand physics at the macroscale. Yet, the question remains how this can be justified based on a microscopic quantu…
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…
Non-Markovian Quantum Process Tomography
Gregory A. L. White, Felix A. Pollock, Lloyd C. L. Hollenberg +2
Characterisation protocols have so far played a central role in the development of noisy intermediate-scale quantum (NISQ) computers capable of impressive quantum feats. This traje…
Signatures of quantum chaos in an out-of-time-order tensor
Magdalini Zonnios, Jesper Levinsen, Meera M. Parish +2
Motivated by the famous ink-drop experiment, where ink droplets are used to determine the chaoticity of a fluid, we propose an experimentally implementable method for measuring the…
