China’s JiuZhang 3 Quantum Computer Solves Mathematical Problem 20 Billion Years Faster than Supercomputer: Breakthrough in Quantum Computing

Scientists in China have made significant advancements in quantum computing, with their latest prototype, the JiuZhang 3, solving a complex mathematical problem in mere microseconds. This achievement is over 20 billion years faster than the world’s fastest supercomputer could accomplish the same task. The findings were published in the peer-reviewed journal Physical Review Letters.

The JiuZhang series of quantum computers utilizes photons, which are tiny particles that travel at the speed of light, as the medium for calculations. Each photon carries a qubit, which is the basic unit of quantum information. In comparison to its predecessor, the JiuZhang 3 demonstrated a remarkable one million-fold increase in calculation speed.

To put this accomplishment into perspective, the researchers state that the fastest classical supercomputer known as Frontier, developed in the United States and recognized as the most powerful in mid-2022, would require more than 20 billion years to complete the same mathematical problem.

The continuous improvements in the JiuZhang series are credited to the increase in the number of photons used in each iteration. The first version had 76 photons, followed by 113 in the second version, and now an impressive 255 photons in the latest iteration.

This breakthrough in quantum computing marks a significant stride towards solving complex problems at an unprecedented speed. While further advancements are still needed, the recent achievements in quantum computing bring immense potential for revolutionizing various fields that heavily rely on complex calculations.
