Optimized double-pulse laser shapes from D-MORPH quantum optimal control achieve ~99% Bell-state fidelity in Rydberg atoms and remain robust to moderate amplitude noise while phase noise remains the dominant limiter.
Random global pulses in Rydberg chains generate states with Haar-like statistics at long times for weak interactions, while optimal control prepares generic symmetric states with infidelities from 10^{-5} to 3e-2 for 9 spins, worsening with entanglement entropy.
