Dissociation of vortex stacks into fractional-flux vortices
A. De Col, V. B. Geshkenbein, G. Blatter
We discuss the zero field superconducting phase transition in a finite system of magnetically coupled superconducting layers. Transverse screening is modified by the presence of ot…
Entanglement in Mesoscopic Structures: Role of Projection
A. V. Lebedev, G. Blatter, C. W. J. Beenakker +1
We present a theoretical analysis of the appearance of entanglement in non-interacting mesoscopic structures. Our setup involves two oppositely polarized sources injecting electron…
Appearance of Schrodinger Cat States in the Measurement Process
G. B. Lesovik, A. V. Lebedev, G. Blatter
Although quantum mechanics is a mature theory, fundamental problems discussed during its time of foundation have remained with us to this day. These problems are centered on the pr…
Topologically protected quantum bits from Josephson junction arrays
L. B. Ioffe, M. V. Feigel'man, A. Ioselevich +3
All physical implementations of quantum bits (qubits), carrying the information and computation in a putative quantum computer, have to meet the conflicting requirements of environ…
Transport in a One-Dimensional Superfluid: Quantum Nucleation of Phase Slips
H. P. Büchler, V. B. Geshkenbein, G. Blatter
We present an analytical derivation for the quantum decay rate of the superflow through a weak link in a one-dimensional Bose-Einstein-condensate. The effective action for the phas…
Andreev Spectroscopy for Superconducting Phase Qubits
Mikhail V. Feigel'man, Lev B. Ioffe, Vadim B. Geshkenbein +1
We propose a new method to measure the coherence time of superconducting phase qubits based on the analysis of the magnetic-field dependent dc nonlinear Andreev current across a hi…
