To summarize the experiment - they measured the interference effects of electron waves from a hydrogen molecule hit by xrays (high energy photons) and the electron wave interference pattern carried with it information on the relative timing of photon absorption at two ends of the molecule. So using this interference-based "amplification" they could resolve and infer the propagation of the photon across the molecule length scale. Or at least this is how I interpreted it from a coarse read :)
There was no clocks and detectors involved that you might think of at first.
- goldenkey 6y agoThanks for your explanation. This makes a lot of sense. A carrier signal is generated (as high as 10^27) [1] - modulated by some observable - and then recorded and analyzed. The highest resolution event that will be visible in the waveform will be 1/(2f) where f is the frequency of the carrier signal. The 1/2 factor is due to the sampling theorem [2].
