Double-Slit Experiment
Interference arises from phase alignment during commit. A detector resets the pattern by creating a new particle under the CBF new-particle rule.
- Wave propagation: A photon or electron leaves its source as a coherent field of wave cells. Each cell carries phase and direction data in T. The Event Ledger buffers all potential paths as uncommitted options.
- Slit diversification: Passing through two slits diversifies the set of momentum vectors kᵢ. Their relative phases beat against each other, and the ledger’s temporal gate prefers commit points where phases align (Δθ ≈ 0). The observed intensity pattern follows |Σ e^{iθᵢ}|², the Born-rule map.
- Commit event: The final detection is a single commit that satisfies all four gates—temporal, spatial, conservation, and informational. The pattern of likely commits emerges statistically from phase-matched candidates, not from multiple particles interfering with themselves in real space.
- Adding a detector: Placing a sensor or quantum dot near a slit changes the ledger structure. The detector absorbs or re-emits a particle, triggering the new-particle rule: the old interference network is cleared, and a new rounded wavefront begins from the detection site.
- Result: With both slits open and unmeasured, the commit field spans both paths, producing an interference map. When a slit is monitored, the event chain is reset at the detector, collapsing the multi-path coherence into a single emission.
- Why this matters: The pattern changes because the causal structure changed, not because the particle “knew” it was observed. Every detection spawns a fresh source, preserving causality and enforcing forward-only ledger growth.
