On the unraveling of open quantum dynamics
Brecht I. C Donvil, Paolo Muratore-Ginanneschi
It is well known that the state operator of an open quantum system can be generically represented as the solution of a time-local equation -- a quantum master equation. Unraveling…
Solving the time-complexity problem and tuning the performance of quantum reservoir computing by artificial memory restriction
Saud Čindrak, Brecht Donvil, Kathy Lüdge +1
Quantum reservoir computing is a computing approach which aims at utilising the complexity and high-dimensionality of small quantum systems, together with the fast trainability of…
Quantum Trajectory Approach to Error Mitigation
Brecht. I. C Donvil, Rochus Lechler, Joachim Ankerhold +1
Quantum Error Mitigation (EM) is a collection of strategies to reduce errors on noisy intermediate scale quantum (NISQ) devices on which proper quantum error correction is not feas…
Single Qubit Error Mitigation by Simulating Non-Markovian Dynamics
Mirko Rossini, Dominik Maile, Joachim Ankerhold +1
Quantum simulation is a powerful tool to study the properties of quantum systems. The dynamics of open quantum systems are often described by Completely Positive (CP) maps, for whi…
Unraveling-paired dynamical maps can recover the input of quantum channels
Brecht Donvil, Paolo Muratore-Ginanneschi
We explore algebraic and dynamical consequences of unraveling general time-local master equations. We show that the "influence martingale", the paramount ingredient of a recently d…
Apparent Heating due to Imperfect Calorimetric Measurements
Brecht Donvil, Joachim Ankerhold
Performing imperfect or noisy measurements on a quantum system both impacts the measurement outcome and the state of the system after the measurement. In this paper we are concerne…
Interference of Quantum Trajectories
Brecht Donvil, Paolo Muratore-Ginanneschi
We extend quantum trajectory theory to encompass the evolution of a large class of open quantum systems interacting with an environment at {arbitrary coupling strength}. Specifical…
Hybrid master equation for calorimetric measurements
Brecht Donvil, Paolo Muratore-Ginanneschi, Jukka P. Pekola
Ongoing experimental activity aims at calorimetric measurements of thermodynamic indicators of quantum integrated systems. We study a model of a driven qubit in contact with a fini…
A model for calorimetric measurements in an open quantum system
Brecht Donvil, Paolo Muratore-Ginanneschi, Jukka P. Pekola +1
We investigate the experimental setup proposed in [New J. Phys., 15, 115006 (2013)] for calorimetric measurements of thermodynamic indicators in an open quantum system. As theoreti…
Thermodynamics of a Periodically Driven Qubit
Brecht Donvil
We aim to give a pedagogic presentation of the open system dynamics of a periodically driven qubit in contact with a temperature bath. We are specifically interested in the thermod…
