Abstract
Photon-mediated interactions in quantum systems represent a crucial point in quantum mechanics for the design and analysis of scalable quantum information systems. In this communication we numerically demonstrate that quantum emitters can interact coherently with a sub-wavelength plasmonic nano-cavity. In particular, we report how the interplay between the near field of quantum emitters and the gap plasmon field can induce a striking canalization of the emission. This effect is observed in a cascade of metal–insulator–metal nanostructures (MIM), interlocked by a nano-cavity containing the quantum emitters, where the selective reshaping of the radiated field occurs. Our study pave the way for the implementation of cavity-mediated quantum gates and for the realization of scalable and tunable quantum systems.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
