On the numerical characterization of atmospheric effects on an Earth-Space quantum communication channel
N. Antonietti, M. Mondin, G. Brida +1
Earth-Space quantum communication is the next challenge of telecommunications. As long as we want to know the outcome of a quantum communication by means of single photons, we have…
Quantum phase transitions and quantum fidelity in free fermion graphs
M. Cozzini, P. Giorda, P. Zanardi
In this paper we analyze the ground state phase diagram of a class of fermionic Hamiltonians by looking at the fidelity of ground states corresponding to slightly different Hamilto…
Quantum geometry and quantum algorithms
S. Garnerone, A. Marzuoli, M. Rasetti
Motivated by algorithmic problems arising in quantum field theories whose dynamical variables are geometric in nature, we provide a quantum algorithm that efficiently approximates…
Quantum Knitting
S. Garnerone, A. Marzuoli, M. Rasetti
We analyze the connections between the mathematical theory of knots and quantum physics by addressing a number of algorithmic questions related to both knots and braid groups. Knot…
Ground state fidelity and quantum phase transitions in free Fermi systems
P. Zanardi, M. Cozzini, P. Giorda
We compute the fidelity between the ground states of general quadratic fermionic hamiltonians and analyze its connections with quantum phase transitions. Each of these systems is c…
Classical and quantum q-deformed physical systems
A. Lavagno, A. M. Scarfone, P. Narayana Swamy
On the basis of the non-commutative q-calculus, we investigate a q-deformation of the classical Poisson bracket in order to formulate a generalized q-deformed dynamics in the class…
