    The device measures photons in one second, perhaps, and doesn't measure a single photon, which could be a graviton or something as small as Planck length.

    Great presentation!

    5:12 "Every photon you send on the mode interacts with the atom"
    Sorry I'm new to this stuff. What is a mode?

      A mode is just one way the laser cavity can oscillate , like a guitar string when plucked will oscillate transversely , a spoke on a bike wheel when plucked will oscillate transversely giving out a little dampened ping. When you cycle down the road the spoke that is perpendicular to the wheel's point of contact induces a longitudinal vibration which is in ultra sound range you don't hear it but dogs do ...that's why they chase posties on bikes, that's the dogs modus operandi.

    In theoretical physics, what if photon is actually two photons sharing the same room.

      Time to reflect.

      In experimental physics high flux lasers can kick an electron up to a virtual level (that doesn't exist) and results in a still bound electron, if you get another photon along quickly enough you get two photon ionisation. This is used in RIMS, resonant ionisation mass spectroscopy! Yes you are right on!
