Add to FacebookOne of the most surprising consequences of quantum mechanics isthe entanglement of two or more distant particles. Even thoughthere are still open questions regarding some fundamental issuesrelated to entangled systems, quantum entanglement has started toplay important roles in practical applications. Quantum imaging isone of the hot topics. Quantum imaging has many interestingfeatures which are useful for different applications. Forexample, quantum imaging can be nonlocal, which is useful forsecure two-dimensional information transfer. Quantum imaging canreach a much higher spatial resolution compared with classicalimaging, even beyond the diffraction limit. This is useful forlithography and other microsystems fabrication technology. Thesuper-resolution does not represent a violation of the uncertaintyprinciple, it is just a quantum multi-particle phenomenon. Canquantum imaging be simulated classically? This question isclosely related to the concerns of Einstein-Podolsky-Rosen of1935. An attempted answer is given based on the analysis of arecent experiment of biphoton imaging-interference/diffraction.
