Supermartingales in Quantum Resources Theories: Where do quantum resources go when you're watching?
Katarzyna Macieszczak, Robert L. Jack
We establish a connection between quantum resource theory and probability theory, under repeated application of free operations. We show that strong monotonicity of a resource meas…
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…
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…
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)…
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…
Heterogeneous nucleation in the random field Ising model
Liheng Yao, Robert L. Jack
We investigate the nucleation dynamics of the three-dimensional random field Ising model (RFIM) under an external field. We use umbrella sampling to compute the free-energy cost of…
Unravelling Metastable Markovian Open Quantum Systems
Calum A. Brown, Katarzyna Macieszczak, Robert L. Jack
We analyse the dynamics of metastable Markovian open quantum systems by unravelling their average dynamics into stochastic trajectories. We use quantum reset processes as examples…
