New nonlinearities discovered in single-photon detectors beyond current theoretical models by researchers of @prfupol. doi.org/10.1063/5.0106… @OpticsOlomouc @UPOlomouc

Scientific Visualization : Python + @matplotlib (labri.fr/perso/nrougier…) 60,000 downloads, 5500 ★, 360 forks, 35$ tips in one week. Huge success (moderately for tips).

We report on anomalous supralinearity of single-photon avalanche diodes and superconducting nanowire single-photon detectors. It cannot be explained using known theoretical models. arxiv.org/abs/2109.08347 @PepaHlousek @IvoStraka @QuantumHedgehog

@TatevChalyan @QuantERA_EU @OpticsOlomouc @QuantumHedgehog @PhotonicsMeetup I'm sorry that I missed this question; I just noticed it now. At the moment, we are not planning to go in this direction. However, if someone in the QKD community decides to simulate temporal correlations in channel fading, this could be a way to go.

@IvoStraka @QuantERA_EU @OpticsOlomouc @QuantumHedgehog @PhotonicsMeetup Indeed, it is. Do you think about moving towards quantum security problems?

@TatevChalyan @QuantERA_EU @OpticsOlomouc @QuantumHedgehog @PhotonicsMeetup The wavelength is arbitrary; it was most convenient in terms of equipment to measure it somewhere around 810 nm.

@IvoStraka @QuantERA_EU @OpticsOlomouc @QuantumHedgehog @PhotonicsMeetup Thanks for sharing with this nice work. However, what are the potential applications you are targeting? And why exactly 814nm?

We have looked into actively quenched SPADs🔈 and their detection statistics under continuous illumination💡📈. If you use SPADs to measure CW light, check out our paper!📝 quantum.opticsolomouc.org/archives/2357 @IvoStraka @QuantumHedgehog

@jindrichsidlo @IvoStraka Myslím, že ano. Vtip je virálnější, širší vymezení vůči ostatním a zanadávání, kterému lidi vždy rádi přitakají.

@jindrichsidlo Slabota, ten vtip s Čechem, Avatarem a partou komunistů prospěl Zemanovi určitě víc.
