Controlled creation of a singular spinor vortex by circumventing the Dirac belt trick
L. S. Weiss, M. O. Borgh, A. Blinova +4
Persistent topological defects and textures are particularly dramatic consequences of superfluidity. Among the most fascinating examples are the singular vortices arising from the…
Decay of a Quantum Knot
T. Ollikainen, A. Blinova, M. Möttönen +1
We experimentally study the dynamics of quantum knots in a uniform magnetic field in spin-1 Bose-Einstein condensates. The knot is created in the polar magnetic phase, which rapidl…
Quantum knots in Bose-Einstein condensates created by counterdiabatic control
T. Ollikainen, S. Masuda, M. Möttönen +1
We theoretically study the creation of knot structures in the polar phase of spin-1 BECs using the counterdiabatic protocol in an unusual fashion. We provide an analytic solution t…
Quantum Gates for Propagating Microwave Photons
Roope Kokkoniemi, Tuomas Ollikainen, Russell E. Lake +6
We report a generic scheme to implement transmission-type quantum gates for propagating microwave photons, based on a sequence of lumped-element components on transmission lines. B…
