Cryogenic microwave source based on nanoscale tunnel junctions
Shumpei Masuda, Kuan Y. Tan, Matti Partanen +5
We experimentally realize an incoherent microwave source driven by voltage-controlled quantum tunneling of electrons through nanoscale normal-metal--insulator--superconductor junct…
Efficient protocol for qubit initialization with a tunable environment
Jani Tuorila, Matti Partanen, Tapio Ala-Nissila +1
We propose an efficient qubit initialization protocol based on a dissipative environment that can be dynamically adjusted. Here the qubit is coupled to a thermal bath through a tun…
Experimental realization of a Dirac monopole through the decay of an isolated monopole
T. Ollikainen, K. Tiurev, A. Blinova +3
We experimentally observe the decay dynamics of deterministically created isolated monopoles in spin-1 Bose-Einstein condensates. As the condensate undergoes a change between magne…
Counter-diabatic vortex pump in spinor Bose-Einstein condensates
T. Ollikainen, S. Masuda, M. Möttönen +1
Topological phase imprinting is a well-established technique for deterministic vortex creation in spinor Bose-Einstein condensates of alkali metal atoms. It was recently shown that…
Energy-Efficient Quantum Computing
Joni Ikonen, Juha Salmilehto, Mikko Möttönen
In the near future, a major challenge in quantum computing is to scale up robust qubit prototypes to practical problem sizes and to implement comprehensive error correction for com…
Evolution of an isolated monopole in a spin-1 Bose-Einstein condensate
Konstantin Tiurev, Pekko Kuopanportti, András Márton Gunyhó +2
We simulate the decay dynamics of an isolated monopole defect in the nematic vector of a spin-1 Bose-Einstein condensate during the polar-to-ferromagnetic phase transition of the s…
