Les cryptographes examinent le brouillage quantique pour aborder la causalité dans les communications sécurisées.
Le sujet se concentre sur le maintien de la sécurité dans un environnement post-quantique en étudiant les principes de cause à effet.
Physicists at MIT have developed a theoretical technique inspired by the film Interstellar to send messages backwards in time using quantum entanglement. The approach mimics closed time-like curves and surprisingly improves communication through noisy channels. While actual time travel remains impossible, the idea could enhance conventional systems.

Researchers at Los Alamos National Laboratory have developed quantum control techniques that can make systems appear to reverse the flow of time. The work, published in Physical Review X, uses measurements and feedback to manipulate the perceived direction of time in quantum processes.
A mathematical study concludes that consciousness cannot arise purely from quantum processes. Researchers at Chapman University found that the no-cloning theorem prevents the information copying required for agency.

Scientists at California Polytechnic State University have discovered new forms of quantum matter by varying magnetic fields over time. The breakthrough, detailed in Physical Review B, shows that time-dependent control can produce stable quantum states without static equivalents. This could advance quantum computing by making systems more resistant to errors.
