Summary:

- Researchers in China have developed a quantum computer that can break military-grade encryption, including RSA and AES, in a matter of seconds. This represents a significant breakthrough in quantum computing capabilities.
- The quantum computer, called Jiuzhang 2, is able to perform complex calculations exponentially faster than classical computers, making it a potential threat to current encryption methods used to protect sensitive data and communications.
- The development highlights the rapid progress being made in quantum computing and the need for the development of new, quantum-resistant encryption methods to protect against the growing threat of quantum hacking.
