We present a microwave photon detection scheme based on wavelength conversion in hybrid cavity system (electro-opto-mechanical converter). By converting microwave pulse into optical pulse efficiently, tough microwave photon detection can be switched to convenient optical photon detection. We demonstrate that a theoretical detection efficiency analogous to optical detection efficiency can be reached by selecting proper parameters. Pulse shapes of both wavelengths match well. Furthermore, we enhance the scheme by applying the Josephson parametric amplifier (JPA) and optical parametric amplifier (OPA) in the respective cavity, and we obtain a maximum detection efficiency enhancement of near 41% compared to the non-amplification case.
