quasiparticles

A University of Pennsylvania research team has demonstrated on-chip photonic quantum skyrmion transfer, publishing the result in Nature Physics. Skyrmions are topological quasiparticle-like structures, and achieving their controlled transfer on a photonic chip could matter for future quantum information and photonic technologies. The demonstration marks a step in bringing topological quantum phenomena onto integrated optical hardware.

Researchers report that quantum skyrmions — tiny topological spin structures usually studied in magnetic materials — have been produced and guided on a photonic chip, marking a step toward integrated quantum photonic devices. The work suggests exotic quasiparticles can be controlled with light on chip-scale hardware, drawing interest from physicists working on quantum information and topological systems.
