Tying Quantum Knots
David S. Hall, Michael W. Ray, Konstantin Tiurev +3
Knots are familiar entities that appear at a captivating nexus of art, technology, mathematics, and science. As topologically stable objects within field theories, they have been s…
Detection of zeptojoule microwave pulses using electrothermal feedback in proximity-induced Josephson junctions
J. Govenius, R. E. Lake, K. Y. Tan +1
We experimentally investigate and utilize electrothermal feedback in a microwave nanobolometer based on a normal-metal ($\mbox{Au}_{x}\mbox{Pd}_{1-x}$) nanowire with proximity-indu…
Observation of quantum-limited heat conduction over macroscopic distances
Matti Partanen, Kuan Yen Tan, Joonas Govenius +4
The emerging quantum technological apparatuses [1,2], such as the quantum computer [3-5], call for extreme performance in thermal engineering at the nanoscale [6]. Importantly, qua…
Parity measurement of remote qubits using dispersive coupling and photodetection
J. Govenius, Y. Matsuzaki, I. G. Savenko +1
Parity measurement is a key step in many entanglement generation and quantum error correction schemes. We propose a protocol for non-destructive parity measurement of two remote qu…
Decay of an isolated monopole into a Dirac monopole configuration
K. Tiurev, E. Ruokokoski, H. Mäkelä +2
We study numerically the detailed structure and decay dynamics of isolated monopoles in conditions similar to those of their recent experimental discovery. We find that the core of…
Quantum Treatment for Bose-Einstein Condensation in Non-Equilibrium Systems
H. Flayac, I. G. Savenko, M. Möttönen +1
We develop an approach based on stochastic quantum trajectories for an incoherently pumped system of interacting bosons relaxing their energy in a thermal reservoir. Our approach e…
