Discord and non-classicality in probabilistic theories

Paolo Perinotti

Quantum discord quantifies non-classical correlations in quantum states. We introduce discord for states in causal probabilistic theories, inspired by the original definition propo…

Memory cost of quantum protocols

Alessandro Bisio, Giacomo Mauro D'Ariano, Paolo Perinotti +1

In this paper we consider the problem of minimizing the ancillary systems required to realize an arbitrary strategy of a quantum protocol, with the assistance of classical memory.…

Experimental implementation of unambiguous quantum reading

Michele Dall'Arno, Alessandro Bisio, Giacomo Mauro D'Ariano +3

We provide the optimal strategy for unambiguous quantum reading of optical memories, namely when perfect retrieving of information is achieved probabilistically, for the case where…

BF-theory in graphene: a route toward topological quantum computing?

Annalisa Marzuoli, Giandomenico Palumbo

Besides the plenty of applications of graphene allotropes in condensed matter and nanotechnology, we argue that graphene sheets might be engineered to support room-temperature topo…

Chaos and statistical relaxation in quantum systems of interacting particles

L. F. Santos, F. Borgonovi, F. M. Izrailev

We propose a method to study the transition to chaos in isolated quantum systems of interacting particles. It is based on the concept of delocalization of eigenstates in the energy…

Quantum measurement bounds beyond the uncertainty relations

Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone

We give a bound to the precision in the estimation of a parameter in terms of the expectation value of an observable. It is an extension of the Cramer-Rao inequality and of the Hei…

Classical Dynamics of Quantum Entanglement

Giulio Casati, Italo Guarneri, Jose Reslen

We numerically analyze the dynamical generation of quantum entanglement in a system of 2 interacting particles, started in a coherent separable state, for decreasing values of $\hb…

Quantum computation with programmable connections between gates

Timoteo Colnaghi, Giacomo Mauro D'Ariano, Paolo Perinotti +1

A new model of quantum computation is considered, in which the connections between gates are programmed by the state of a quantum register. This new model of computation is shown t…

Phase estimation via quantum interferometry for noisy detectors

Nicoló Spagnolo, Chiara Vitelli, Vito Giovanni Lucivero +3

The sensitivity in optical interferometry is strongly affected by losses during the signal propagation or at the detection stage. The optimal quantum states of the probing signals…

Experimental Realization of Optimal Noise Estimation for a General Pauli Channel

A. Chiuri, V. Rosati, G. Vallone +5

We present the experimental realization of the optimal estimation protocol for a Pauli noisy channel. The method is based on the generation of 2-qubit Bell states and the introduct…

Tradeoff between energy and error in the discrimination of quantum-optical devices

Alessandro Bisio, Michele Dall'Arno, Giacomo Mauro D'Ariano

We address the problem of energy-error tradeoff in the discrimination between two linear passive quantum optical devices with a single use. We provide an analytical derivation of t…

Cloning of a quantum measurement

Alessandro Bisio, Giacomo Mauro D'Ariano, Paolo Perinotti +1

We analyze quantum algorithms for cloning of a quantum measurement. Our aim is to mimic two uses of a device performing an unknown von Neumann measurement with a single use of the…

Informational power of quantum measurements

Michele Dall'Arno, Giacomo Mauro D'Ariano, Massimiliano F. Sacchi

We introduce the informational power of a quantum measurement as the maximum amount of classical information that the measurement can extract from any ensemble of quantum states. W…

Quantum learning algorithms for quantum measurements

Alessandro Bisio, Giacomo Mauro D'Ariano, Paolo Perinotti +1

We study quantum learning algorithms for quantum measurements. The optimal learning algorithm is derived for arbitrary von Neumann measurements in the case of training with one or…

Advances in Quantum Metrology

Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone

In classical estimation theory, the central limit theorem implies that the statistical error in a measurement outcome can be reduced by an amount proportional to n^(-1/2) by repeat…

Extremal quantum protocols

Giacomo Mauro D'Ariano, Paolo Perinotti, Michal Sedlak

Generalized quantum instruments correspond to measurements where the input and output are either states or more generally quantum circuits. These measurements describe any quantum…
