State of the art and prospects for quantum computing
M. I. Dyakonov
This is a brief review of the experimental and theoretical quantum computing. The hopes for eventually building a useful quantum computer rely entirely on the so-called "threshold…
Revisiting the hopes for scalable quantum computation
M. I. Dyakonov
The hopes for scalable quantum computing rely on the "threshold theorem": once the error per qubit per gate is below a certain value, the methods of quantum error correction allow…
Three-body amplification of photon heat tunneling
Riccardo Messina, Mauro Antezza, Philippe Ben-Abdallah
Resonant tunneling of surface polaritons across a subwavelength vacuum gap between two polar or metallic bodies at different temperatures leads to an almost monochromatic heat tran…
Dynamics of an elementary quantum system in environments out of thermal equilibrium
Bruno Bellomo, Riccardo Messina, Mauro Antezza
We study the internal dynamics of an elementary quantum system placed close to a body held at a temperature different from that of the surrounding radiation. We derive general expr…
Dynamics of quantum correlations in two-qubit systems within non-Markovian environments
Rosario Lo Franco, Bruno Bellomo, Sabrina Maniscalco +1
Knowledge of the dynamical behavior of correlations with no classical counterpart, like entanglement, nonlocal correlations and quantum discord, in open quantum systems is of prima…
Quantum systems in a stationary environment out of thermal equilibrium
Bruno Bellomo, Riccardo Messina, Didier Felbacq +1
We discuss how the thermalization of an elementary quantum system is modified when the system is placed in an environment out of thermal equilibrium. To this aim we provide a detai…
