China has revealed a new light-based quantum computer that has set a world speed record for the quantity of “detected photons.” Developed by a team led by Chinese physicist Pan Jianwei, Jiuzhang 3.0 boasts 255 detected photons, surpassing the 113 of Jiuzhang 2.0 and the 76 of the original Jiazhang quantum computer.
According to Chinese state media, Jiuzhang 3.0 is a million times faster than Jiuzhang 2.0. When it comes to solving problems related to Gaussian boson sampling, a mathematical model is suitable for quantum computing. It is claimed that Jiuzhang 3.0 can handle the most intricate Gaussian boson sampling tasks in a single microsecond. Whereas the world’s fastest supercomputer “Frontier” would require over 20 billion years to complete the same task.
The research conducted by Pan’s team has been published online in the American scientific journal Physical Review Letters.
Pan Jianwei highlighted the potential of quantum computers. He stated that they have inherently rapid parallel computing capabilities. And are expected to offer enhanced computing power, particularly through specific algorithms. This advancement is anticipated to benefit various fields, including code deciphering, big data optimization, weather forecasting, material design, and drug analysis.
However, it’s worth noting that different types of quantum computers have unique approaches and capabilities, making direct comparisons challenging. There are three primary categories of quantum computers. Those based on electrons (superconducting), atoms (cold atoms or trapped ions), and photons or light-based systems.
While this quantum computing development is significant, some technology experts caution against drawing direct comparisons between various quantum computer types due to their differing methodologies and capacities.
