Optimal estimation of quantum observables
Giacomo Mauro D'Ariano, Vittorio Giovannetti, Paolo Perinotti
We consider the problem of estimating the ensemble average of an observable on an ensemble of equally prepared identical quantum systems. We show that, among all kinds of measureme…
A dynamical model for quantum memory channels
Vittorio Giovannetti
A dynamical model for quantum channel is introduced which allows one to pass continuously from the memoryless case to the case in which memory effects are present. The quantum and…
Robust gates for holonomic quantum computation
G. Florio, P. Facchi, R. Fazio +2
Non Abelian geometric phases are attracting increasing interest because of possible experimental application in quantum computation. We study the effects of the environment (modell…
Quantum metrology
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
We point out a general framework that encompasses most cases in which quantum effects enable an increase in precision when estimating a parameter (quantum metrology). The typical q…
Improved transfer of quantum information using a local memory
Vittorio Giovannetti, Daniel Burgarth
We demonstrate that the quantum communication between two parties can be significantly improved if the receiver is allowed to store the received signals in a quantum memory before…
Information transmission through lossy bosonic memory channels
Giovanna Ruggeri, Giulio Soliani, Vittorio Giovannetti +1
We study the information transmission through a quantum channel, defined over a continuous alphabet and losing its energy en route, in presence of correlated noise among different…
