Preparation and manipulation of a fault-tolerant superconducting qubit
Mateusz Cholascinski, Yuriy Makhlin, Gerd Schön
We describe a qubit encoded in continuous quantum variables of an rf superconducting quantum interference device. Since the number of accessible states in the system is infinite, w…
Stabilized parametric Cooper-pair pumping in a linear array of coupled Josephson junctions
Mateusz Cholascinski, Ravindra W. Chhajlany
We present an experimentally realizable stabilized charge pumping scheme in a linear array of Cooper-pair boxes. The system design intrinsically protects the pumping mechanism from…
Geometry of an adiabatic passage at a level crossing
Mateusz Cholascinski
We discuss adiabatic quantum phenomena at a level crossing. Given a path in the parameter space which passes through a degeneracy point, we find a criterion which determines whethe…
Appearance of Topological Phases in Superconducting Nanocircuits
Mateusz Cholascinski
We construct non-Abelian geometric transformations in superconducting nanocircuits, which resemble in properties the Aharonov-Bohm phase for an electron transported around a magnet…
Quantum holonomies with Josephson-junction devices
Mateusz Cholascinski
We examined properties of a Josephson-junction system composed of two coupled Cooper-pair boxes (charge qubits) as a candidate for observation of quantum holonomies. We construct a…
