Shadows and photon rings of a quantum black hole

Physics Letters B
Recently, a black hole model in loop quantum gravity has been proposed by Lewandowski, Ma, Yang and Zhang (2023) [34]. The metric tensor of the quantum black hole (QBH) is a suitably modified Schwarzschild one.

Enhancement of and interference among higher order multipole transitions in molecules near a plasmonic nanoantenna

Nature Communications, 2019
Here, the authors study the interference effects between different multipole transition channels by coupling a molecule to a plasmonic nanoantenna. Controlling different emission pathways of quantum emitters allows selective enhancement or suppression of

Imaging Through Noise With Quantum Illumination

, 2019
The contrast of an image can be degraded by the presence of background light and sensor noise. To overcome this degradation, quantum illumination protocols have been theorised (Science 321 (2008), Physics Review Letters 101 (2008)) that exploit the ...
