Quantum Left-handed metamaterial with superconducting quantum interference devices [PDF]

open access: yesarXiv, 2005
A scheme of left-handed metamaterial (LHM) composed of superconducting quantum interference devices (SQUIDs) and conducting wires is proposed. The permeability of a probe field can be smoothly tuned over a wide range with another electromagnetic (coupling) field due to quantum interference effect.

Quantum modulation against electromagnetic interference [PDF]

open access: yesarXiv, 2014
Periodic signals in electrical and electronic equipment can cause interference in nearby devices. Randomized modulation of those signals spreads their energy through the frequency spectrum and can help to mitigate electromagnetic interference problems. The inherently random nature of quantum phenomena makes them a good control signal.

Beyond Quantum interference and Optical pumping: invoking a Closed-loop phase [PDF]

open access: yesarXiv, 2016
Atomic coherence effects arising from coherent light-atom interaction are conventionally known to be governed by quantum interference and optical pumping mechanisms. However, anisotropic nonlinear response driven by optical field involves another fundamental effect arising from closed-loop multiphoton transitions.
