Signal modulation is one of the most basic and important concepts in the RF industry. It consists of using the variation of one or more parameters of a carrier signal to transmit information, ...

The stability of motional-mode frequency is essential for realizing high-fidelity quantum gates in trapped-ion quantum computing. While broadband Gaussian noise has been extensively studied and ...

This study presents a dual-frequency modulation scheme in which both optical and microwave fields are simultaneously modulated in a microwave–optical double resonance system within a hot rubidium ...
