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 Circuits Architecture
Giulio Chiribella, Giacomo Mauro D'Ariano, Paolo Perinotti
We present a method for optimizing quantum circuits architecture. The method is based on the notion of "quantum comb", which describes a circuit board in which one can insert varia…
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…
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…
Optimal estimation of ensemble averages from a quantum measurement
Paolo Perinotti, Giacomo M. D'Ariano
We consider the general measurement scenario in which the ensemble average of an operator is determined via suitable data-processing of the outcomes of a quantum measurement descri…
