Our paper entitled “Direct Detection of a Single Photon by Humans” by Tinsley J. N. et. al., has been published in Nature Communications.

In this study we have shown that humans are capable of detecting a single photon onto their eyes with a probability above chance. This was done by developing a quantum light source based on spontaneous parametric down-conversion (SPDC) which can generate single-photon states of light and combining it with a state-of-the-art psychophysics procedure. Thereby we could show that the human visual system including the post-processing performed by the retina and the brain can detect a single photon incident onto the eye.
