""The trick lies in the fact that local decoherence acts in a preferred direction, which is perpendicular to the one in which coherence is measured," Adesso explained. "Consequently, the resulting quantum states are overall degraded by such noise, but their observed coherence remains unaffected during the dynamics if the initial conditions are suitably chosen.""

Отмечается также, что это может объяснить и квантовые эффекты в биологии:
"Besides technological innovations, the results may also shed light on the quantum coherence that occurs naturally in biological systems, such as the light-harvesting systems in plants. Previous research has shown that some biological systems can maintain quantum coherence for very long times in certain noisy environments."
