Accurate Truncations of Chain Mapping Models for Open Quantum Systems

open access: yesNanomaterials, 2021
The dynamics of open quantum systems are of great interest in many research fields, such as for the interaction of a quantum emitter with the electromagnetic modes of a nanophotonic structure.

Universal Fidelity Reduction of Quantum Operations from Weak Dissipation. [PDF]

open access: yesPhysical Review Letters, 2021
Quantum information processing is in real systems often limited by dissipation, stemming from remaining uncontrolled interaction with microscopic degrees of freedom.

Algebraic theory of quantum synchronization and limit cycles under dissipation [PDF]

open access: yesSciPost Physics, 2021
Synchronization is a phenomenon where interacting particles lock their motion and display non-trivial dynamics. Despite intense efforts studying synchronization in systems without clear classical limits, no comprehensive theory has been found. We develop

Quantum Dissipative Rashba Spin Ratchets [PDF]

open access: yesPhysical Review Letters, 2008
We predict the possibility to generate a finite stationary spin current by applying an unbiased ac driving to a quasi-one-dimensional asymmetric periodic structure with Rashba spin-orbit interaction and strong dissipation. We show that under a finite coupling strength between the orbital degrees of freedom the electron dynamics at low temperatures ...

Exponential time-scaling of estimation precision by reaching a quantum critical point

open access: yesPhysical Review Research, 2022
Quantum metrology refers to the use of quantum resources in parameter-estimation protocols, aiming at enhancing its precision. The quantum Fisher information is a key quantity in this context, setting the ultimate achievable precision with respect to ...

Quantum measurement and decoherence [PDF]

open access: yes, 2001
Distribution functions defined in accord with the quantum theory of measurement are combined with results obtained from the quantum Langevin equation to discuss decoherence in quantum Brownian motion. Closed form expressions for wave packet spreading and
