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

We can designate such photon-matter interactions enabled by reciprocal light confinement through BICs with truly open systems as reciprocal QED, which holds great promise to comprehend and extend cavity QED for optics, photonics, and related fields.

C2weakest assumption

That bound states in the continuum provide a form of light confinement in reciprocal space that is fundamentally distinct from and extends traditional cavity QED in truly open systems.

C3one line summary

The paper designates photon-matter interactions enabled by reciprocal light confinement through BICs in open systems as reciprocal QED.
