Harnessing Brillouin interaction in rare-earth aluminosilicate glass microwires for optoelectromechanic quantum transduction

Quantum transduction, the process of converting quantum signals from one form energy to another is a key step in harnessing different physical platforms and associated qubits for information processing. Optoelectromechanics has been effective approaches undertake transduction optical-to-microwave signals, among others such as those using atomic ensembles, collective magnetostatic spin excitations, piezoelectricity electro-optomechanical resonator Silicon nitride membrane. One areas loss photon conversion rate optoelectromechanical method nanomembranes electro-optic conversion. To address this, we propose use Brillouin interactions fiber mode that allowed be passed through taper rare-earth Aluminium glass microwires. It suggests can efficiently convert $195.57$ THz optical signal $325.08$ MHz microwave with help interactions, whispering stimulated scattering yielding efficiency $\sim45$\%.
