Could (or has) the quantum clock mentioned here be used to more accuretly measure gravitational anomalies? Isn’t an ability to measure minute gravatitional effects missing from the tools of physics? What about again re measuring G. Could it ever be possible to measure the gravitational effects between atoms indipendent of earts gravity? Are such studies even possible?

I just want to say that as a student I found your lecture notes on quantum computation to be excellent. Thank you for making them freely available!

Maybe OT : In Leyden is a headstone for Ludolph van Ceulen (1540-1610) who manually calculted PI, first he reached 20, then 32, then finally 35 digits. These 35 are carved on his gravestone in the church in Leyden.

So, John Preskill, what’s your choice of quantum poison: Parallel worlds? Reality isn’t there until you look? Hidden variables? Instrumentalism?
