Chinese scientists claim a breakthrough quantum computer

Chinese scientists claim to have built quantum computers capable of performing certain computations nearly 100 trillion times faster than the world’s most advanced supercomputers – a first milestone in the country’s efforts to develop technology.

Researchers have built a prototype quantum computer, which is exponentially faster than existing supercomputers, said the state-run Xinhua news agency, citing research published in Science magazine.

This breakthrough represents the advantage of quantum computing, also known as quantum supremacy, where no traditional computer can perform the same task in a reasonable amount of time and is unlikely to be undone by algorithmic or hardware upgrades, according to research.

While still in its infancy, quantum computing is seen as the key to radically increasing the processing speed and power of computers, enabling them to simulate large systems and driving advances in physics, chemistry and other fields.

The technology race

Chinese researchers are competing with major US companies from Google Alphabet Inc to Amazon. com and Microsoft to take the lead in technology, which has become another front in the US-China technology race.

Google said last year it had built a computer that can perform computations in 200 seconds that would take the fastest supercomputer in about 10,000 years to achieve quantum supremacy. Chinese researchers claim their new prototype is capable of processing 10 billion times faster than the Google prototype, according to the Xinhua report.

Xi Jinping’s government is building a $ 10 billion National Quantum Information Science Laboratory as part of a major push in the field. In the US, the Trump administration provided $ 1 billion in funding for artificial intelligence and quantum information research earlier this year and has sought to take credit for Google’s 2019 breakthrough. – Bloomberg
