has anyone with better number theory / probability skills than me taken a
stab at exactly *how* accurate cloning would have to be (and how many
clones you would need) to determine accurately both the bit and filter
values for a quantum key exchange photon? for a single pass (5/6 photons
output) it feels like the odds are stacked against getting a clean
reading; for two passes (25/36) it feels even worse.
how accurate would cloning need to be to get a better than 1/3 failure
rate?
