Enhancement of transmission rates in quantum memory channels with damping
G. Benenti, A. D'Arrigo, G. Falci
We consider the transfer of quantum information down a single-mode quantum transmission line. Such quantum channel is modeled as a damped harmonic oscillator, the interaction betwe…
Memory effects in a Markov chain dephasing channel
Antonio D'Arrigo, Elena De Leo, Giuliano Benenti +1
We study a dephasing channel with memory, modelled by a Markov chain. We show that even weak memory effects have a detrimental impact on the performance of quantum error correcting…
Memory effects in quantum information transmission across a Hamiltonian dephasing channel
A. D'Arrigo, G. Benenti, G. Falci
We study a dephasing channel with memory, modelled by a multimode environment of oscillators. Focusing on the case of two channel uses, we show that memory effects can enhance the…
Quantum Capacity of a dephasing channel with memory
Antonio D'Arrigo, Giuliano Benenti, Giuseppe Falci
We show that the amount of coherent quantum information that can be reliably transmitted down a dephasing channel with memory is maximized by separable input states. In particular,…
Dynamical entanglement-transfer for quantum information networks
M. Paternostro, W. Son, M. S. Kim +2
A key element in the architecture of a quantum information processing network is a reliable physical interface between fields and qubits. We study a process of entanglement transfe…
Entanglement between two superconducting qubits via interaction with non-classical radiation
Mauro Paternostro, Giuseppe Falci, Myungshik Kim +1
We propose a scheme to physically interface superconducting nano-circuits and quantum optics. We address the transfer of quantum information between systems having different physic…
