Correlation Imaging via Hybrid Entanglement between Microwave Photons and Surface Acoustic Wave Phonons
The work proposes a correlation imaging technique using hybrid entanglement between microwave photons and surface acoustic wave phonons. By matching frequencies but exploiting their vastly different wavelengths, this resource allows for two complementary imaging modalities: demagnification of macroscopic objects onto microscopic chips and magnification of microscopic objects into macroscopic devices. This enables cross-scale quantum sensing.
