As Boyd recalls, he then remembered that Robert Millikan, a Nobel Prize - winning physicist and the head of Caltech from 1921 to 1945, also had to contend with removing copper oxide when he performed his famous 1916 experiment to measure Planck's constant, which is important for calculating the amount of energy a single particle of light, or photon, Boyd wondered if he, like Millikan, could devise a method for cleaning his copper while it was under vacuum conditions.

The new light source could be further used to investigate how the quantum efficiency varies with wavelength, since it is easy to vary the wavelength of the generated single photons.

People can detect flashes of light as feeble as a single photon, an experiment has demonstrated — a finding that seems to conclude a 70 - year quest to test the limits of human vision.

This is because only single or a handful of entangled photons can be produced with the available technology, and this number is too low for the human eye to perceive these photons as light.

In contrast, the light source developed by Leonid Krivitsky and co-workers at the A * STAR Data Storage Institute and A * STAR Institute of Medical Biology is a truly single - photon source and hence eliminates the need to statistically analyze measurement results, thus enhancing measurement accuracy1.
