Can a more entangled quantum state lose its entanglement faster?

Just as hot water can freeze faster than cold water, a pair of qubits starting with stronger entanglement can lose all quantum correlations sooner than a less-entangled pair exposed to the same noisy environment. By solving the dynamics analytically for amplitude damping reservoirs, the authors map exactly which initial states show this counterintuitive crossing — and when entanglement abruptly hits zero (entanglement sudden death) ahead of the 'colder' state. The result has direct implications for how long quantum resources survive in realistic devices.
