Two-excitation routing via linear quantum channels
Tony John George Apollaro, Wayne Jordan Chetcuti
Routing quantum information among different nodes in a network is a fundamental prerequisite for a quantum internet. While single-qubit routing has been largely addressed, many-qub…

Fisher-information-based estimation of optomechanical coupling strengths
Claudio Sanavio, József Zsolt Bernád, André Xuereb
The formalism of quantum estimation theory, focusing on the quantum and classical Fisher information, is applied to the estimation of the coupling strength in an optomechanical sys…

Multipartite entanglement transfer in spin chains
Tony J. G. Apollaro, Claudio Sanavio, Wayne Jordan Chetcuti +1
We investigate the transfer of genuine multipartite entanglement across a spin-1/2 chain with nearest-neighbor XX-type interaction. We focus on the perturbative regime, where a blo…
