Advancements in Quantum Networks: Unlocking New Realms with Nanometric Optomechanical Cavities

Researchers at the State University of Campinas (UNICAMP) in Brazil, in collaboration with colleagues at ETH Zurich and TU Delft, have conducted a study on the use of nanometric optomechanical cavities for the development of advanced quantum networks. The study introduces dissipative optomechanics, allowing for direct scattering of photons from the waveguide to the resonator, enabling tighter control of optoacoustic interaction. The researchers achieved a tenfold rise in the optomechanical coupling rate and raised the mechanical frequency by two orders of magnitude, offering promising prospects for more effective devices. The study also lays the foundation for future research in manipulating mechanical modes individually and mitigating optical non-linearities in optomechanical devices.
