Solid-State Quantum Communication With Josephson Arrays
Alessandro Romito, Rosario Fazio, C. Bruder
Josephson junction arrays can be used as quantum channels to transfer quantum information between distant sites. In this work we discuss simple protocols to realize state transfer…
The charge shuttle as a nanomechanical ratchet
F. Pistolesi, Rosario Fazio
We consider the charge shuttle proposed by Gorelik {\em et al.} driven by a time-dependent voltage bias. In the case of asymmetric setup, the system behaves as a rachet. For pure A…
Continuous measurements of two qubits
Wenjin Mao, Dmitri V. Averin, Francesco Plastina +1
We develop a theory of coherent quantum oscillations in two, in general interacting, qubits measured continuously by a mesoscopic detector with arbitrary non-linearity and discuss…
Dynamical Imperfections in quantum computers
Paolo Facchi, Simone Montangero, Rosario Fazio +1
We study the effects of dynamical imperfections in quantum computers. By considering an explicit example, we identify different regimes ranging from the low-frequency case, where t…
Chaotic dynamics in superconducting nanocircuits
Simone Montangero, Alessandro Romito, Giuliano Benenti +1
The quantum kicked rotator can be realized in a periodically driven superconducting nanocircuit. A study of the fidelity allows the experimental investigation of exponential instab…
Information-capacity description of spin-chain correlations
Vittorio Giovannetti, Rosario Fazio
Information capacities achievable in the multi-parallel-use scenarios are employed to characterize the quantum correlations in unmodulated spin chains. By studying the qubit amplit…
