Another study was done last year and they also found humans can probably see single photons, though the study is limited as its sample size is n=3.

Photons don't exist in the first place. Science has moved on and modern models don't assume the existence of actual particles. It's only electromagnetic waves.
Not that I understand quantum mechanics.
How do you live with that?
Like it or not, in modern physics, "photon" refers to a particular type of discrete lump of momentum and energy. It is a thing you can definitely have one of.
