Spin_Up, Soft_Latch, and Instant Collapse_ re_reading attosecond entanglement timing through the GUR memory field lens

This manuscript reinterprets recent attosecond pump–probe measurements of two-electron entanglement timing through the lens of the Great Universal Recycle (GUR) framework. It identifies a two-stage process—a finite “soft-latch” build-up interval followed by an effectively instantaneous collapse event—and maps each stage onto GUR’s tri-phase collapse cycle (Futureᵤᵣ → Nowᵣ → Thenᵤᵣ). Drawing on experiments at TU Wien and mid-circuit erasure synchrony in neutral-atom qubits, the study argues that the observed ~200 as delay reflects a pre-collapse handshake (soft-latch) rather than any time-extended collapse. It proposes scaled variants—from attosecond twin-peak tests to bench-scale timing assays—to further probe the soft-latch window and confirm GUR’s “instant-on” collapse hypothesis.
