Security experts caution against sensationalizing Chinese researchers' claims of cracking military-grade encryption using quantum computing, highlighting that the attack was on a 22-bit key, far shorter than commonly used keys, and that practical quantum threats to current encryption are still far off due to environmental interference and immature hardware, emphasizing the need for caution and discussion on quantum readiness without being alarmist.
