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…
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…
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…
Operational approach to metastability
Katarzyna Macieszczak
In this work, we introduce an information-theoretic approach for considering changes in dynamics of finitely dimensional open quantum systems governed by master equations. This exp…
Hierarchical classical metastability in an open quantum East model
Dominic C. Rose, Katarzyna Macieszczak, Igor Lesanovsky +1
We study in detail an open quantum generalisation of a classical kinetically constrained model -- the East model -- known to exhibit slow glassy dynamics stemming from a complex hi…
