IEEE Journal of the Electron Devices Society allows an early open access to the paper "Characterization of Quanta Image Sensor Pump-Gate Jots with Deep Sub-electron Read Noise" by Jiaju Ma, Dakota Starkey, Arun Rao, Kofi Odame, and Eric R. Fossum of Dartmouth College. The paper reports noise of the best pixel in the array of 0.22e-:
The average pixel noise was somewhat higher:
And here is the image lag measurements:
