Abstract
A method of imaging includes generating a set of four entangled photons including a first, a second, a third, and a fourth entangled photon that are correlated in time, wherein any one pair of the four entangled photons correlated in time indicates that all four of the entangled photons are entangled. The first, second, third, and fourth entangled photon are coupled to respective ones of a first, second, third, and fourth path. A modulation of the second entangled photon is generated from a first object positioned at a first object plane and is detected. A modulation of the third entangled photon is generated from a second object positioned at a second object plane and is detected. A modulation of the fourth entangled photon is generated from a third object positioned at a third object plane and is detected. Coincidences between a spatially-resolved detection of the first entangled photon and a detection of at least one of the second entangled photon, the third entangled photon, and the fourth entangled photon are then determined. Image information about at least one of the first, second and third object is determined using the determined coincidences.
