Key Points

The approach enhances transduction efficiency without adding noise, implying a significant advancement in quantum technology.
Efficiency improvements involve microwave-microwave two-mode squeezing operations in quantum transduction.
Concatenating operations leads to better optical-to-microwave transduction outcomes when intraband entanglement is maximized.
The method highlights the potential of using entanglement to overcome traditional limitations in quantum transducers.

Implication

This method demonstrates improved efficiency in quantum transduction, utilizing entanglement to reduce noise.

Abstract

We propose to noiselessly boost the efficiency of conventional quantum transducers by consuming intraband entanglement. For example, by concatenating microwave-microwave two-mode squeezing operations with the transducer, the protocol amplifies optical-to-microwave transduction efficiency without added noise.
