Variable range cotunneling and conductivity of a granular metal
M. V. Feigel'man, A. S. Ioselevich
The Efros-Shklovskii law for the conductivity of granular metals is interpreted as a result of a variable range cotunneling process. The cotunneling between distant resonant grains…
Quantum percolation in granular metals
M. V. Feigel'man, A. S. Ioselevich, M. A. Skvortsov
Theory of quantum corrections to conductivity of granular metal films is developed for the realistic case of large randomly distributed tunnel conductances. Quantum fluctuations of…
Protected Qubits and Chern Simons theories in Josephson Junction Arrays
B. Doucot, M. V. Feigel'man, L. B. Ioffe +1
We present general symmetry arguments that show the appearance of doubly denerate states protected from external perturbations in a wide class of Hamiltonians. We construct the sim…
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…
