Exact Resource Laws for Passive Wavelength Routing in Entanglement Networks
Ekta Panwar, Gilberto Borges, Saeid Salari +5
Entanglement-based networks provide a scalable framework for multiuser quantum communication by passively routing spectrally correlated photon pairs across interconnected nodes. Se…
Phase transition of the four-dimensional cross-polytope model
Roman Krcmar, Andrej Gendiar, Peter Rapcan +1
Thermodynamic properties of the four-dimensional cross-polytope model, the 16-cell model, which is an example of higher dimensional generalizations of the octahedron model, are stu…
Entanglement can preserve the compact nature of the phase-space occupancy
Andre M. C. Souza, Peter Rapčan, Constantino Tsallis
We study the one-dimensional transverse-field spin-1/2 Ising ferromagnet at its critical point. We consider an -sized subsystem of a -sized ring, and trace over the states of…
Nonlinear inhomogeneous Fokker-Planck equations: entropy and free-energy time evolution
Gabriele Sicuro, Peter Rapčan, Constantino Tsallis
We extend a recently introduced free-energy formalism for homogeneous Fokker-Planck equations to a wide, and physically appealing, class of inhomogeneous nonlinear Fokker-Planck eq…
Direct estimation of decoherence rates
Vladimír Bužek, Peter Rapcan, Jochen Rau +1
The decoherence rate is a nonlinear channel parameter that describes quantitatively the decay of the off-diagonal elements of a density operator in the decoherence basis. We addres…
Scavenging quantum information: Multiple observations of quantum systems
Peter Rapcan, John Calsamiglia, Ramon Munoz-Tapia +2
Given an unknown state of a qudit that has already been measured optimally, can one still extract any information about the original unknown state? Clearly, after a maximally infor…
