Estimation of two-qubit interactions through channels with environment assistance
Milajiguli Rexiti, Stefano Mancini
We consider the estimation of two-qubit interactions when initial states of both qubit can be locally controlled, while the final state of only one qubit can be measured. This amou…
Tomographic portrait of quantum channels
G. G. Amosov, S. Mancini, V. I. Man'ko
We formulate the notion of quantum channels in the framework of quantum tomography and address there the issue of whether such maps can be regarded as classical stochastic maps. In…
Quantum information transmission through a qubit chain with quasi-local dissipation
Roya Radgohar, Laleh Memarzadeh, Stefano Mancini
We study quantum information transmission in a Heisenberg-XY chain where qubits are affected by quasi-local environment action and compare it with the case of local action of the e…
Universal feedback control of two-qubit entanglement
Morteza Rafiee, Alireza Nourmandipour, Stefano Mancini
We consider two-qubit undergoing local dissipation and subject to local driving. We then determine the optimal Markovian feedback action to preserve initial entanglement as well as…
Quantum channels from reflections on moving mirrors
G. Gianfelici, S. Mancini
Light reflection on a mirror can be thought as a simple physical effect. However if this happens when the mirror moves a rich scenario opens up. Here we aim at analyzing it from a…
Gaussian two-mode attacks in one-way quantum cryptography
Carlo Ottaviani, Stefano Mancini, Stefano Pirandola
We investigate the asymptotic security of one-way continuous variable quantum key distribution against Gaussian two-mode coherent attacks. The one-way protocol is implemented by ar…
