Abstract
One of the most surprising consequences of quantum mechanics is the entanglement of two or more distant particles. Even though there are still open questions regarding some fundamental issues related to entangled systems, quantum entanglement has started to play important roles in practical applications. Quantum imaging is one of the hot topics. Quantum imaging has many interesting features which are useful for different applications. For example, quantum imaging can be nonlocal, which is useful for secure two-dimensional information transfer. Quantum imaging can reach a much higher spatial resolution compared with classical imaging, even beyond the diffraction limit. This is useful for lithography and other microsystems fabrication technology. The super-resolution does not represent a violation of the uncertainty principle, it is just a quantum multi-particle phenomenon. Can quantum imaging be simulated classically? This question is closely related to the concerns of Einstein-Podolsky-Rosen of 1935. An attempted answer is given based on the analysis of a recent experiment of biphoton imaging-interference/diffraction.
