Interference Search — Grover-inspired multi-hypothesis search

📡

Interference Search

Grover-inspired amplitude amplification for parallel hypothesis testing on Channel State Information feature spaces. Probes 64 hypothesis lattice points in superposition and amplifies whichever signature matches the live CSI window.

Hypothesis count (N)

Lattice size. Optimal iterations grow as ⌊π/4·√N⌋.

Iterations cap

Stop after this many Grover diffusions if no peak detected.

Detection threshold

0.85

Fire hypothesis_found when peak amplitude exceeds this.

CSI window length

Subcarriers consumed per oracle query.

Noise sigma

0.08

Simulated channel noise injected into oracle.
