Probabilistic theories with purification

G. Chiribella, G. M. D'Ariano, P. Perinotti

We investigate general probabilistic theories in which every mixed state has a purification, unique up to reversible channels on the purifying system. We show that the purification…

Microscopic description of 2d topological phases, duality and 3d state sums

Zoltan Kadar, Annalisa Marzuoli, Mario Rasetti

Doubled topological phases introduced by Kitaev, Levin and Wen supported on two dimensional lattices are Hamiltonian versions of three dimensional topological quantum field theorie…

Pseudo-classical theory for fidelity of nearly resonant quantum rotors

Martina Abb, Italo Guarneri, Sandro Wimberger

Using a semiclassical ansatz we analytically predict for the fidelity of delta-kicked rotors the occurrence of revivals and the disappearance of intermediate revival peaks arising…

A short impossibility proof of Quantum Bit Commitment

G. Chiribella, G. M. D'Ariano, P. Perinotti +2

Bit commitment protocols, whose security is based on the laws of quantum mechanics alone, are generally held to be impossible on the basis of a concealment-bindingness tradeoff. A…

Theoretical framework for quantum networks

Giulio Chiribella, Giacomo M. D'Ariano, Paolo Perinotti

We present a framework to treat quantum networks and all possible transformations thereof, including as special cases all possible manipulations of quantum states, measurements, an…

Optimal quantum learning of a unitary transformation

A. Bisio, G. Chiribella, G. M. D'Ariano +2

We address the problem of learning an unknown unitary transformation from a finite number of examples. The problem consists in finding the learning machine that optimally emulates…

Probability-fidelity tradeoffs for targeted quantum operations

G. M. D'Ariano, S. Facchini, P. Perinotti +1

We present probability-fidelity tradeoffs for a varying quantum operation with fixed input-output states and for a varying inversion of a fixed quantum operation.

Renormalized quantum tomography

G. M. D'Ariano, M. F. Sacchi

The core of quantum tomography is the possibility of writing a generally unbounded complex operator in form of an expansion over operators that are generally nonlinear functions of…

Quantum and semiclassical spin networks: from atomic and molecular physics to quantum computing and gravity

V. Aquilanti, A. C. P. Bitencourt, C. da S. Ferreira +2

The mathematical apparatus of quantum--mechanical angular momentum (re)coupling, developed originally to describe spectroscopic phenomena in atomic, molecular, optical and nuclear…
