Pushing the limits in real-time measurements of quantum dynamics

E Kleinherbers, P Stegmann, A Kurzmann, M Geller… - Physical Review Letters, 2022 - APS
Time-resolved studies of quantum systems are the key to understanding quantum dynamics
at its core. The real-time measurement of individual quantum numbers as they switch …

Lee-Yang theory of Bose-Einstein condensation

F Brange, T Pyhäranta, E Heinonen, K Brandner… - Physical Review A, 2023 - APS
Bose-Einstein condensation happens as a gas of bosons is cooled below its transition
temperature, and the ground state becomes macroscopically occupied. The phase transition …

Photon emission statistics of a driven microwave cavity

P Portugal, F Brange, KSU Kansanen… - Physical Review …, 2023 - APS
Recent experimental advances have made it possible to detect individual quantum jumps in
open quantum systems, such as the tunneling of single electrons in nanoscale conductors or …

Radiation statistics of a degenerate parametric oscillator at threshold

F Hassler, S Kim, L Arndt - SciPost Physics, 2023 - scipost.org
As a function of the driving strength, a degenerate parametric oscillator exhibits an instability
at which spontaneous oscillations occur. Close to threshold, both the nonlinearity as well as …

[HTML][HTML] A High-Reliability Quantum Communication Protocol via Controllable-Signal Attenuation

Y Zhang, Y Chen, M Shi, Q Zhou, C Liu - Photonics, 2024 - mdpi.com
Since the protocol for counterfactual quantum communication was proposed, complete
counterfactuality can be achieved as there are no physical particles in the transmission …

Detection of Quantum Phase Transitions with a Lee-Yang Formalism and Many-Body Algorithms

PM Vecsei - 2025 - aaltodoc.aalto.fi
Phase transitions in many-body quantum systems arise from the collective behaviour of
many degrees of freedom. For many interacting quantum many-body systems, it remains …
