We study quantum entanglement, quantum imaging, and atomic physics. Entangled photons exhibit nonclassical characteristics and can be used for quantum imaging. Unlike classical optical imaging, quantum imaging has achieved sub-shot noise and super-resolution beyond the diffraction limit through coincidence detection. As photons originate from atoms/molecules, we also investigate atomic physics at the interface between classical and quantum physics. For example, we surprisedly found that the Bloch equation conventionally thought as classical only yields the von Neumann equation and the Schrödinger equation for spin-half particles. We also developed a theory that models the multi-stage Stern-Gerlach experiment suggested by Heisenberg and Einstein more accurately than the available theory.
