Damn, it wasn't so easy to find the article, because TFA doesn't explicitly provide author names, even. But the link in the image title led to Fein et al. (2019).[0]
So what I'm curious about is how far apart those "Two Places at Once" are. And if I'm understanding Fig. 2 correctly, it's large. That is ...
> Fig. 2 | interference data. a, Counts as a function of the transverse position of the third grating with a sine-fit (solid black line) yielding a visibility of 25 ± 3%. The optical grating power was 1.2 W for this single scan. Counts are dark-rate-corrected and normalized to the control measurements.
... with peaks at ~200 nm, ~430 nm, ~680 nm and ~900 nm.
But a 25 kDa molecule is only ~4 nm in diameter.[1]
That's amazing!
