Recently, Google announced to the world that the quantum computer it is building, called Sycamore, only needs a few minutes to make calculations that would take a classic computer about 10,000 years. Now we are hearing news that the newest and one of the most advanced quantum computers in the world from China has broken this record.
Scientists working on a future machine called Jiuzhang performed in just 180 seconds an extremely complex simulation on their new quantum computer. It turns out that creating a similar simulation would take the world's most powerful supercomputer, Fugaku, 600 million years, and the Chinese Sunway TaihuLight, the third fastest in the world, even 2.5 billion years.
We are talking about a machine that is 100 trillion times faster than the fastest supercomputers that humanity is currently calculating on. Remember, however, that currently available quantum computers are in fact only in their infancy, so it's scary to think what performance they will offer in a few years, let alone decades of development.
The Chinese Jiuzhang functions a bit differently from the rest of the more universal quantum computers developed in the world. He has his own unique features that give him an advantage over them, but also limp in some matters. Scientists believe, however, that such its structure is supposed to allow you to start enjoying the benefits of these machines in everyday life. Jiuzhang can work in a slightly warmer environment than Google or IBM computers, but it is only adapted to some kind of computation.
During record-breaking calculations, a Chinese quantum computer sent laser pulses, which were then inserted into a maze of 300 beam splitters and 75 mirrors. Calculations were possible using the so-called sampling boson. In practice, when we direct the light beam to the distributor, after the light beam hits it, the beam will split into two traveling in different directions. If individual photons hit, they will go in the same direction.
When we direct a sufficiently powerful beam of light towards the distributor, it will divide it into several beams that will be directed in different directions. Subsequent splitters will break the streams of smaller beams again, which will result in the creation epicmovienews countless branches. A classical computer cannot compute these paths, while a quantum computer does it perfectly.
Chinese scientists report that during the experiment, the Jiuzhang computer sent out laser pulses that were injected into a maze of 300 beam splitters and 75 mirrors. Now engineers intend to gradually expand their machine and start using it in practical calculations for the development of the aviation and space industry.
