Strong coupling theory for driven tunneling and vibrational relaxation
M. Thorwart, M. Grifoni, P. Hänggi
We investigate on a unified basis tunneling and vibrational relaxation in driven dissipative multistable systems described by their N lowest lying unperturbed levels. By use of the…
Motional Squashed States
Stefano Mancini, David Vitali, Paolo Tombesi
We show that by using a feedback loop it is possible to reduce the fluctuations in one quadrature of the vibrational degree of freedom of a trapped ion below the quantum limit. The…
Stabilizing Quantum Information
Paolo Zanardi
The dynamical-algebraic structure underlying all the schemes for quantum information stabilization is argued to be fully contained in the reducibility of the operator algebra descr…
Non-Abelian Berry connections for quantum computation
Jiannis Pachos, Paolo Zanardi, Mario Rasetti
In the holonomic approach to quantum computation information is encoded in a degenerate eigenspace of a parametric family of Hamiltonians and manipulated by the associated holonomi…
Holonomic Quantum Computation
Paolo Zanardi, Mario Rasetti
We show that the notion of generalized Berry phase i.e., non-abelian holonomy, can be used for enabling quantum computation. The computational space is realized by a -fold degen…
Generating entangled superpositions of macroscopically distinguishable states within a parametric oscillator
Francesco De Martini, Mauro Fortunato, Paolo Tombesi +1
We suggest a variant of the recently proposed experiment for the generation of a new kind of Schroedinger-cat states, using two coupled parametric down-converter nonlinear crystals…
Non-Markovian quantum feedback from homodyne measurements: the effect of a non-zero feedback delay time
Vittorio Giovannetti, Paolo Tombesi, David Vitali
We solve exactly the non-Markovian dynamics of a cavity mode in the presence of a feedback loop based on homodyne measurements, in the case of a non-zero feedback delay time. With…
Computation on a Noiseless Quantum Code and Symmetrization
Paolo Zanardi
Let be the state-space of a quantum computer coupled with the environment by a set of error operators spanning a Lie algebra Suppose admits a nois…
