Adiabatically steered open quantum systems: Master equation and optimal phase
J. Salmilehto, P. Solinas, J. Ankerhold +1
We introduce an alternative way to derive the generalized form of the master equation recently presented by J. P. Pekola et al. [Phys. Rev. Lett. 105, 030401 (2010)] for an adiabat…
Ground-state geometric quantum computing in superconducting systems
P. Solinas, J. -M. Pirkkalainen, M. Möttönen
We present a theoretical proposal for the implementation of geometric quantum computing based on a Hamiltonian which has a doubly degenerate ground state. Thus the system which is…
Decoherence of adiabatically steered quantum systems
P. Solinas, M. Möttönen, J. Salmilehto +1
We study the effect of Markovian environmental noise on the dynamics of a two-level quantum system which is steered adiabatically by an external driving field. We express the maste…
Stabilization and pumping of giant vortices in dilute Bose-Einstein condensates
Pekko Kuopanportti, Mikko Möttönen
Recently, it was shown that giant vortices with arbitrarily large quantum numbers can possibly be created in dilute Bose-Einstein condensates by cyclically pumping vorticity into t…
Environmentally Activated Tunneling Events in a Hybrid Single-Electron Box
O. -P. Saira, M. Mottonen, V. F. Maisi +1
We have measured individual tunneling events and Coulomb step shapes in single-electron boxes with opaque superconductor-normal metal tunnel junctions. We observe anomalous broaden…
Single-shot readout of an electron spin in silicon
Andrea Morello, Jarryd J. Pla, Floris A. Zwanenburg +12
The size of silicon transistors used in microelectronic devices is shrinking to the level where quantum effects become important. While this presents a significant challenge for th…
