On truncations of hierarchical equations of motion for finite-dimensional systems
Vasilii Vadimov
We study truncations of hierarchical equations of motion (HEOM) for finite-dimensional open quantum systems. We prove that for finite-dimensional approximations constructed with a…
Autonomous quantum heat engine
Tuomas Uusnäkki, Miika Rasola, Vasilii Vadimov +3
Quantum heat engines provide attractive means in quantum thermodynamics for studying the fundamentals of the flow of heat and work. Previous experimental implementations of heat en…
Quantum dial
Aashish Sah, Suman Kundu, Priyank Singh +3
Accurate control of quantum degrees of freedom is promising for sensing, communication, and computing, but building a useful quantum computer faces a central isolation-and-control…
Simulating Non-Markovian Dynamics in Open Quantum Systems
Meng Xu, Vasilii Vadimov, J. T. Stockburger +1
Recent advances in quantum technologies and related experiments have created a need for highly accurate, versatile, and computationally efficient simulation techniques for the dyna…
Proposal for an autonomous quantum heat engine
Miika Rasola, Vasilii Vadimov, Tuomas Uusnäkki +1
We propose and theoretically analyse a superconducting electric circuit which can be used to experimentally realize an autonomous quantum heat engine. Using a quasiclassical, non-M…
Dissipation and noise in strongly driven Josephson junctions
Vasilii Vadimov, Yoshiki Sunada, Mikko Möttönen
In circuit quantum electrodynamical systems, the quasiparticle-related losses in Josephson junctions are suppressed due to the gap in the superconducting density of states which is…
