PRISM: Phase-Only LM via FFT Interference

What Changed

Enforces unit-magnitude (|z|=1) to store info in phase angles, inspired by RoPE

Why It Matters

Challenges traditional magnitude-based signaling in LMs, potentially enabling physics-mimicking architectures efficient on photonic hardware. Reveals interference limits, inspiring hybrid models with fewer params.

What To Do Next
