On the complexity of controlling quantum many-body dynamics
T. Caneva, A. Silva, R. Fazio +3
We demonstrate that arbitrary time evolutions of many-body quantum systems can be reversed even in cases when only part of the Hamiltonian can be controlled. The reversed dynamics…
Quantum Billiards in Optical Lattices
Simone Montangero, Diego Frustaglia, Tommaso Calarco +1
We study finite two dimensional spin lattices with definite geometry (spin billiards) demonstrating the display of collective integrable or chaotic dynamics depending on their shap…
Cloning transformations in spin networks without external control
G. De Chiara, R. Fazio, C. Macchiavello +2
In this paper we present an approach to quantum cloning with unmodulated spin networks. The cloner is realized by a proper design of the network and a choice of the coupling betwee…
Entanglement production by quantum error correction in the presence of correlated environment
G. De Chiara, R. Fazio, C. Macchiavello +1
We analyze the effect of a quantum error correcting code on the entanglement of encoded logical qubits in the presence of a dephasing interaction with a correlated environment. Suc…
