Key Findings
The “Jiuzhang 4” optical quantum computing prototype, led by the University of Science and Technology of China, received the Leading Technology Award at the 2026 World Internet Conference on November 2. It was one of only two basic research achievements selected from over 430 entries submitted by 43 countries and regions.
Technical Details
In solving the specific mathematical problem of Gaussian Boson Sampling, Jiuzhang 4 generated a sample in 25 microseconds. In comparison, the El Capitan supercomputer, using the most advanced classical algorithms, would require more than 10^42 years to complete the same task. This represents a computational speed increase of 10^54 times over the supercomputer, establishing a new world record in optical quantum computing.
Background and Context
The acceleration of quantum computing has highlighted urgent security vulnerabilities. On March 31, 2026, Google published a white paper estimating that an optimized Shor’s algorithm could derive a private key from a public key for Bitcoin’s Elliptic Curve Cryptography (ECC-256) in 9 minutes, theoretically requiring approximately 500,000 physical qubits.
In response, the U.S. National Institute of Standards and Technology (NIST) released “Transitioning to Post-Quantum Cryptography Standards” on October 27. The guidelines mandate that federal high-value assets and high-impact systems complete the migration of key establishment by the end of 2030 and digital signatures by the end of 2031, with an overall migration target year of 2035.
Significance and Outlook
Engineering responses to these threats are emerging. In September 2026, Xuanyue Technology, incubated by the Zhejiang University Huzhou Research Institute, released the “Xuanyue Tianjian Quantum Zero Trust” system. This system utilizes a hybrid route combining national cryptographic standards with PQC, supporting ML-KEM key encapsulation and ML-DSA digital signatures integrated with the SM2/SM4/TLCP framework. This approach aims to protect data with secrecy cycles of ten or more years against “harvest now, decrypt later” quantum risks.
