At the very outset, one must note that each of the quantum systems is a million times stronger than Google’s Sycamore. Why mention it now, as Chinese scientists claim to create the fastest programmable quantum computers in the world, seeming to solve problems that are presently beyond the capacity of the conventional non-quantum computers.
According to Pan Jianwei from the University of Science and Technology of China (USTC), who heads the team of the researchers, one of the quantum computing systems, Zuchongzhi 2.1 is a million times stronger than its closest rival, Google’s Sycamore. Their programmable superconducting quantum computer, which is named after a 5th-century mathematician, is 10 million times faster compared to the present fastest supercomputer of the world, as claimed by scientists.
Moreover, their photonic quantum computer based on light, called Jiuzhang 2 has the capacity of calculations 100 trillion times faster than the world’s present fastest supercomputer.
In traditional computers, the fundamental unit of information is a bit, and data is mostly stored in binary codes of 1s and 0s. Whereas, quantum computers utilize the special properties of the tiniest particles in the universe which can exist in various states like zeros and ones simultaneously or any position between.
This flexibility of quantum particles lets quantum bits, or qubits, apply which a lot of calculations can be done at the same time said. The Chinese team has developed two different systems. One is the light-based photonic quantum computers, and the other is a superconducting quantum computer that must be kept at very low temperatures for efficient functioning.
Though these machines won’t eradicate classical computers, they may perform certain intricate calculations for short periods.
Pan and his team elaborated that for their system which has 1043 probable results, their photonic quantum computer can sample the output 1024 times quicker compared to a traditional supercomputer.
