Decoherence induced by interacting quantum spin baths

Davide Rossini, Tommaso Calarco, Vittorio Giovannetti +2

We study decoherence induced on a two-level system coupled to a one-dimensional quantum spin chain. We consider the cases where the dynamics of the chain is determined by the Ising…

Robust optimal quantum gates for Josephson charge qubits

Simone Montangero, Tommaso Calarco, Rosario Fazio

Quantum optimal control theory allows to design accurate quantum gates. We employ it to design high-fidelity two-bit gates for Josephson charge qubits in the presence of both leaka…

Sub Shot-Noise interferometric phase sensitivity with Beryllium ions Schroedinger Cat States

Luca Pezzé, Augusto Smerzi

Interferometry with NOON quantum states can provide unbiased phase estimation with a sensitivity scaling as given a prior knowledge that the true phase shift lie…

Decoherence by engineered quantum baths

Davide Rossini, Tommaso Calarco, Vittorio Giovannetti +2

We introduce, and determine decoherence for, a wide class of non-trivial quantum spin baths which embrace Ising, XY and Heisenberg universality classes coupled to a two-level syste…

Theoretical analysis of the implementation of a quantum phase gate with neutral atoms on atom chips

E. Charron, M. A. Cirone, A. Negretti +2

We present a detailed, realistic analysis of the implementation of a proposal for a quantum phase gate based on atomic vibrational states, specializing it to neutral rubidium atoms…
