Quantum state decorrelation
Giacomo M. D'Ariano, Rafal Demkowicz-Dobrzanski, Paolo Perinotti +1
We address the general problem of removing correlations from quantum states while preserving local quantum information as much as possible. We provide a complete solution in the ca…
Quantum indirect estimation theory and joint estimate of all moments of two incompatible observables
Giacomo Mauro D'Ariano, Paolo Perinotti, Massimiliano Federico Sacchi
We introduce the quantum indirect estimation theory, which provides a general framework to address the problem of which ensemble averages can be estimated by means of an available…
Phase-covariant cloning of coherent states
Massimiliano F. Sacchi
We consider the problem of phase-covariant cloning for coherent states. We show that an experimental scheme based on ideal phase measurement and feedforward outperforms the semicla…
Erasable and unerasable correlations
G. M. D'Ariano, R. Demkowicz-Dobrzanski, P. Perinotti +1
We address the problem of removing correlation from sets of states while preserving as much local quantum information as possible. We prove that states obtained from universal clon…
Information-disturbance tradeoff in covariant quantum state estimation
Massimiliano F. Sacchi
We provide a general framework for quantifying the optimal tradeoff between the information retrieved by a quantum measurement and the disturbance on the quantum state in covariant…
