The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

the tunneling ionization of a single sodium atom induced by a 300 nJ BSV beam matches that achieved with a 7.1 μJ coherent light source, demonstrating a dramatic boost in nonlinear efficiency from phase-squeezed quantum light

C2weakest assumption

That differences in ionization yield arise purely from the phase squeezing of the BSV rather than from unaccounted variations in spatial mode, temporal profile, or detection efficiency between the quantum and coherent light setups.

C3one line summary

Bright squeezed vacuum boosts single-atom tunneling ionization to match coherent light using about 24 times less pulse energy, with control via phase squeezing degree.
