Linear Ascending Metrological Algorithm
M. R. Perelshtein, N. S. Kirsanov, V. V. Zemlyanov +4
The ubiquitous presence of shot noise sets a fundamental limit to the measurement precision in classical metrology. Recent advances in quantum devices and novel quantum algorithms…
Open quantum systems beyond Fermi's golden rule: Diagrammatic expansion of the steady-state time-convolutionless master equation
Michael Sven Ferguson, Oded Zilberberg, Gianni Blatter
Steady-state observables, such as occupation numbers and currents, are crucial experimental signatures in open quantum systems. The time-convolutionless (TCL) master equation, whic…
H-theorem and Maxwell Demon in Quantum Physics
N. S. Kirsanov, A. V. Lebedev, I. A. Sadovskyy +4
The Second Law of Thermodynamics states that temporal evolution of an isolated system occurs with non-diminishing entropy. In quantum realm, this holds for energy-isolated systems…
Quantum-enhanced magnetometry by phase estimation algorithms with a single artificial atom
S. Danilin, A. V. Lebedev, A. Vepsäläinen +3
Phase estimation algorithms are key protocols in quantum information processing. Besides applications in quantum computing, they can also be employed in metrology as they allow for…
Trading coherence and entropy by a quantum Maxwell demon
A. V. Lebedev, D. Oehri, G. B. Lesovik +1
The Second Law of Thermodynamics states that the entropy of a closed system is non-decreasing. Discussing the Second Law in the quantum world poses new challenges and provides new…
A tunable, nonlinear Hong-Ou-Mandel interferometer
David Oehri, Mikhail Pletyukhov, Vladimir Gritsev +2
We investigate the two-photon scattering properties of a Jaynes-Cummings (JC) nonlinearity consisting of a two-level system (qubit) interacting with a single mode cavity, which is…
