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