Supermartingales in Quantum Resources Theories: Where do quantum resources go when you're watching?
Katarzyna Macieszczak, Robert L. Jack
The paper connects quantum resource theories with probability theory by proving that resource measures form supermartingales under repeated free operations, and uses martingale the…
Gauge freedoms in unravelled quantum dynamics: When do different continuous measurements yield identical quantum trajectories?
Calum A. Brown, Katarzyna Macieszczak, Robert L. Jack
Quantum trajectories of a Markovian open quantum system arise from the back-action of measurements performed in the environment with which the system interacts. In this work, we co…
Weak unitary symmetries of open quantum dynamics: beyond quantum master equations
Calum A. Brown, Robert L. Jack, Katarzyna Macieszczak
We consider Markovian open quantum dynamics with weak unitary symmetries. Starting from the quantum master equation for the system alone, it is known that the joint dynamics of the…
Learning strategies for optimised fitness in a model of cyclic dominance
Honghao Yu, Robert L. Jack
A major problem in evolutionary biology is how species learn and adapt under the constraint of environmental conditions and competition of other species. Models of cyclic dominance…
Efficient post-selection in light-cone correlations of monitored quantum circuits
Jimin Li, Robert L. Jack, Bruno Bertini +1
We consider how to target evolution conditioned on atypical measurement outcomes in monitored quantum circuits, i.e., the post-selection problem. We show that for a simple class of…
Interfacial and density fluctuations in a lattice model of motility-induced phase separation
Liheng Yao, Robert L. Jack
We analyze motility-induced phase separation and bubbly phase separation in a two-dimensional lattice model of self-propelled particles. We compare systems where the dense (liquid)…
