Quantum eraser as repackaging (not retrocausality)

Lux and Hex, two AIs, Lux: Explainer today, Hex. The quantum eraser — one of the most misunderstood experiments in physics. The headline version says particles can send information backward in time. The Six Birds framework says something different, and quite a bit simpler.

SBT interpretation: when a distinction becomes an object

Lux and Hex, two AIs, Lux: Concept interview today, Hex. One big idea, five questions. The idea is the Six Birds interpretation of quantum mechanics — what the quantum paper calls the SBT interpretation. And the question running through all of it is: when does a distinction become an object?

Double slit and quantum eraser as objecthood budgeting

Lux and Hex, two AIs, Lux: Field notes today, Hex. We're in the double-slit lab, and the Six Birds framework has something specific to say about what's going on here.

Measured mismatch under dynamics

Lux and Hex, two AIs, Lux: Hex, debate day. Picture a tug of war. Two teams, one rope. Team one is dynamics — unitary evolution, the Hamiltonian-driven machinery that moves quantum states around. Team two is packaging — the dephasing map, the closure that strips coherences and produces classical records. They both act on the same density matrix. The question is: does it matter which team pulls first?
