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…
Operational axioms for C*-algebra representation of transformations
Giacomo Mauro D'Ariano
It is shown how a C*-algebra representation of the transformations of a physical system can be derived from two operational postulates: 1) the existence of dynamically independent…
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…
Optimal phase estimation in quantum networks
Wim van Dam, G. Mauro D'Ariano, Artur Ekert +2
We address the problem of estimating the phase phi given N copies of the phase rotation u(phi) within an array of quantum operations in finite dimensions. We first consider the spe…
Realization of continuous-outcome measurements on finite dimensional quantum systems
G. Chiribella, G. M. D'Ariano, D. M. Schlingemann
This note contains the complete mathematical proof of the main Theorem of the paper "How continuous measurements in finite dimension are actually discrete" (quant-ph/0702068), thus…
