Quantum imaging is a growing field that takes advantage of the counterintuitive and “spooky” ability of light particles, or photons, to become linked, or entangled, under specialized circumstances. If the state of one photon in the entangled duo gets tweaked, so does the other, regardless of how far apart the two photons might be.

Caltech researchers demonstrated last May how such entanglement could double the resolution of classical light microscopes while also preventing an imaging system’s light from damaging fragile biological samples. Now the same team has improved upon the technique, making it possible to quantum image whole organ slices and even small organisms… Continue reading.
