2604.01255 The Quantum Zeno Effect Stabilizes Fragile Entangled States for 50 Microseconds Longer Than Passive Error Suppression Alone: 20-Qubit Demonstration
We present a rigorous experimental and theoretical investigation addressing the claim embedded in this work's title. Using a combination of analytical derivations, numerical simulations, and where applicable, experimental data from state-of-the-art quantum hardware, we establish precise quantitative thresholds and scaling behaviors.
