Deterministic Equations for Feedback Control of Open Quantum Systems III: Full counting statistics for jump-based feedback
Alberto J. B. Rosal, Guilherme Fiusa, Patrick P. Potts +1
In this work, we consider a general feedback protocol based on quantum-jump detections, where the last detected jump channel is stored in a memory and subsequently used to implemen…
Deterministic Equations for Feedback Control of Open Quantum Systems II: Properties of the memory function
Alberto J. B. Rosal, Patrick P. Potts, Gabriel T. Landi
Feedback uses past detection outcomes to dynamically modify a quantum system and is central to quantum control. These outcomes can be stored in a memory, defined as a stochastic fu…
Subtleties in the pseudomodes formalism
Wynter Alford, Laetitia P. Bettmann, Gabriel T. Landi
The pseudomode method for open quantum systems, also known as the mesoscopic leads approach, consists in replacing a structured environment by a set of auxiliary "pseudomodes" subj…
Current-based metrology with two-terminal mesoscopic conductors
Shishir Khandelwal, Gabriel T. Landi, Géraldine Haack +1
The traditional approach to quantum parameter estimation focuses on the quantum state, deriving fundamental bounds on precision through the quantum Fisher information. In most expe…
Tightening the thermodynamic uncertainty relations with null-entropy events: What we learn when nothing happens
Abhaya S. Hegde, André M. Timpanaro, Gabriel T. Landi
Fluctuation theorems establish that thermodynamic processes at the microscale can occasionally result in negative entropy production. At the microscale, another distinct possibilit…
Nonequilibrium steady states in multi-bath quantum collision models
Ronan McElvogue, Andrew K. Mitchell, Gabriel T. Landi +1
Collision models provide a simple and versatile setting to capture the dynamics of open quantum systems. The standard approach to thermalisition in this setting involves an environ…
