STUDYING the quantum realm can be illuminating in more senses than one. The special relationship between entangled photons of light could help us gain a clearer picture of things like microscopic structures. High-quality optical imaging involves measuring individual photons reflected off an object. The trouble is that the photons can be deflected en route, and extra photons created by thermal noise can obscure this weakened signal. Seth Lloyd of Massachusetts Institute of Technology suggests that entangled photons could sharpen up such images by providing a way to discard the noise. The properties of entangled particles remain intimately linked,
