Hybrid Six-Level Rydberg Atomic Quantum Receiver for Multi-Band Wireless Communications
Lahiru Shyamal, Harini Hapuarachchi, Saman Atapattu +1
Rydberg atomic quantum receivers (RAQRs) have recently emerged as a promising technology for radio-frequency (RF) reception by directly transducing incident RF fields into optical…
Nitrogen-Vacancy Emission from Nanodiamond: Size, Depth, and Surroundings
Harini Hapuarachchi, Francesco Campaioli, Jared H Cole +2
The negatively charged nitrogen-vacancy (NV) center in diamond is a leading solid-state quantum emitter, offering spin-photon interfaces over a wide temperature range with applicat…
The color center: a ubiquitous visible and near-infrared-II quantum emitter in nitrogen-doped diamond
Brett C. Johnson, Mitchell O. de Vries, Alexander J. Healey +13
Photoluminescent defects in diamond, like the nitrogen-vacancy (NV) color center, are at the forefront of emerging optical quantum technologies. Most emit in the visible and near-i…
Quantum emitter in a plasmonic field: an orientation generalised model
Harini Hapuarachchi, Jesse A. Vaitkus, Jared H. Cole
When a quantum emitter (QE) is placed in close proximity to a plasmonic metal nanoparticle (MNP) within an external optical field, a dipole-dipole coupling arises, resulting in a h…
