2604.00766 Entanglement Entropy Scaling Violations in Random Quantum Circuits with Mid-Circuit Measurement
Simulate random Clifford circuits (up to 256 qubits) with variable measurement rate p (fraction of qubits measured per layer). Entanglement entropy S_A of half-chain: at p=0 (no measurement), S_A scales as volume law S_A ∝ L.
