Theory 11/Quantum Information
Entanglement Spreads at a Front
The claim
Entanglement growth in a chaotic quantum system is set by the operator spreading front rather than by the interaction strength, so stronger coupling can slow apparent growth by reshaping the front.
01The mechanism
Entanglement propagates at a speed set by how operators spread through the system; the front's shape determines the growth curve more than the coupling magnitude.
02Predictions
- P1Growth rate should track front speed.
- P2Stronger coupling need not accelerate growth.
03Refutation
Growth tracking coupling strength would remove the front.
