Born Attention is Linear: Exact Sub-Quadratic Attention and Constant-State Inference from Quantum Measurement

The squared complex inner product has an exact finite feature map, so Born attention runs in linear time with a constant-size state and keeps rotary positions exactly.

Streaming Is Not Memory: Constant-State Born-Attention Byte Models on PG-19

Separates streaming, quality preservation and long-range use, and measures each. Includes a matched Transformer comparison and an ablation of where the gap comes from.
