Above 99.9% Fidelity Single-Qubit Gates, Two-Qubit Gates, and Readout in a Single Superconducting Quantum Device
Fabian Marxer, Jakub Mrożek, Joona Andersson +64
Achieving high-fidelity single-qubit gates, two-qubit gates, and qubit readout is critical for building scalable, error-corrected quantum computers. However, device parameters that…
Beyond hard-core bosons in transmon arrays
Olli Mansikkamäki, Sami Laine, Atte Piltonen +1
Arrays of transmons have proven to be a viable medium for quantum information science and quantum simulations. Despite their widespread popularity as qubit arrays, there remains ye…
Vortex-mediated relaxation of magnon BEC into light Higgs quasiparticles
S. Autti, P. J. Heikkinen, S. M. Laine +4
A magnon Bose-Einstein condensate in superfluid He is a fine instrument for studying the surrounding macroscopic quantum system. At zero temperature, the BEC is subject to a fe…
The phases of the disordered Bose-Hubbard model with attractive interactions
Olli Mansikkamäki, Sami Laine, Matti Silveri
We study the quantum ground state phases of the one-dimensional disordered Bose--Hubbard model with attractive interactions, realized by a chain of superconducting transmon qubits…
Spin wave radiation from vortices in He-B
S. M. Laine, E. V. Thuneberg
We consider a vortex line in the B phase of superfluid He under uniformly precessing magnetization. The magnetization exerts torque on the vortex, causing its order parameter t…
Models for supercritical motion in a superfluid Fermi liquid
J. A. Kuorelahti, S. M. Laine, E. V. Thuneberg
We study the drag force on objects moving in a Fermi superfluid at velocities on the order of the Landau velocity . The expectation has been that is the critical velocit…
Calculation of Leggett-Takagi relaxation in vortices of superfluid 3He-B
S. M. Laine, E. V. Thuneberg
We calculate the relaxation of Brinkman-Smith mode via Leggett-Takagi relaxation in the presence of an isolated vortex in superfluid 3He-B. The calculation is based on an analytica…
