Experimental on-demand recovery of entanglement by local operations within non-Markovian dynamics
Adeline Orieux, Antonio d'Arrigo, Giacomo Ferranti +6
In many applications entanglement must be distributed through noisy communication channels that unavoidably degrade it. Entanglement cannot be generated by local operations and cla…
Entanglement dynamics in superconducting qubits affected by local bistable impurities
Rosario Lo Franco, Antonio D'Arrigo, Giuseppe Falci +2
We study the entanglement dynamics for two independent superconducting qubits each affected by a bistable impurity generating random telegraph noise (RTN) at pure dephasing. The re…
Spin-echo entanglement protection from random telegraph noise
Rosario Lo Franco, Antonio D'Arrigo, Giuseppe Falci +2
We analyze local spin-echo procedures to protect entanglement between two non-interacting qubits, each subject to pure-dephasing random telegraph noise. For superconducting qubits…
Preserving entanglement and nonlocality in solid-state qubits by dynamical decoupling
Rosario Lo Franco, Antonio D'Arrigo, Giuseppe Falci +2
In this paper we study how to preserve entanglement and nonlocality under dephasing produced by classical noise with large low-frequency components, as noise, by Dynamical De…
Dynamical Casimir Effect in Quantum Information Processing
Giuliano Benenti, Antonio D'Arrigo, Stefano Siccardi +1
We demonstrate, in the regime of ultrastrong matter-field coupling, the strong connection between the dynamical Casimir effect (DCE) and the performance of quantum information prot…
Postselection induced entanglement swapping from a vacuum--excitation entangled state to separate quantum systems
Antonio Di Lorenzo
We show that a single particle in a superposition of different paths can entangle two objects located on each path. The entanglement has its maximum visibility for intermediate cou…
