Single-Shot Readout of a Superconducting Qubit Using a Thermal Detector
András M. Gunyhó, Suman Kundu, Jian Ma +8
Measuring the state of qubits is one of the fundamental operations of a quantum computer. Currently, state-of-the-art high-fidelity single-shot readout of superconducting qubits re…
Efficient classical simulation of open bosonic quantum systems
Akseli Mäkinen, Joni Ikonen, Takaaki Aoki +3
We propose a computationally efficient method to solve the dynamics of operators of bosonic quantum systems coupled to their environments. The method maps the operator under intere…
Fast control of dissipation in a superconducting resonator
Vasilii Sevriuk, Kuan Yen Tan, Eric Hyyppä +8
We report on fast tunability of an electromagnetic environment coupled to a superconducting coplanar waveguide resonator. Namely, we utilize a recently-developed quantum-circuit re…
Creation of a Dirac monopole-antimonopole pair in a spin-1 Bose-Einstein condensate
Konstantin Tiurev, Pekko Kuopanportti, Mikko Möttönen
We theoretically demonstrate that a pair of Dirac monopoles with opposite synthetic charges can be created within a single spin-1 Bose-Einstein condensate by steering the spin degr…
Three-dimensional splitting dynamics of giant vortices in Bose-Einstein condensates
Jukka Räbinä, Pekko Kuopanportti, Markus Kivioja +2
We study the splitting dynamics of giant vortices in dilute Bose-Einstein condensates by numerically integrating the three-dimensional Gross-Pitaevskii equation in time. By taking…
Theory of quantum-circuit refrigeration by photon-assisted electron tunneling
Matti Silveri, Hermann Grabert, Shumpei Masuda +2
We focus on a recently experimentally realized scenario of normal-metal-insulator-superconductor tunnel junctions coupled to a superconducting resonator. We develop a first-princip…
