What is it about?

Light–matter interaction in plasmonic lattices is one of the fundamental topics in nano-optics because surface plasmons can spatially confine light at the nanoscale and significantly reduce the mode volume. This paper manipulates light-matter interaction into the strong coupling regime and realizes the photon entanglement in an exciton-free plasmonic lattice system.

Why is it important?

Our work demonstrates a strong coupling system that can be considered an excellent candidate for exploring the physics of the CQED between bosons–bosons and bosons–fermions coupling as well as the potentials of quantum information or quantum communication, which will be utilized in the quantum logic gate and quantum key distribution.


Writing this article was a great pleasure as it has co-authors with whom I have had long-standing collaborations. This article also leads to similar research groups contacting me and ultimately to greater involvement in nanophotonics research.
