China's Jiuzhang is the world's first photonic quantum computer to achieve quantum supremacy on a speed far beyond others.

 

 Chinese quantum computer is 180 million times faster on AI-related tasks, according to the ‘father of quantum’ Pan Jianwei.

 Acknowledgement: When Sam Altman's Loopt came 2005, Peter Klevius had already presented an even better version 2002 but was denied technical help and funding. The idea, according to Peter Klevius wife, emerged already in the late 1990's but was fully outlined when the first true smartphones appeared. It did everything Loopt could do but had also an emotional security "string" in the form of an initial color code on the phone's display (or web site) which indicated a general pattern of interest and readiness to socialize with like-minded people. It was GPS connected so that people could find others in the same area. Moreover, there was a step-wise "opening up" system for safely narrowing each other. People could either display their interest by using the color pattern as a lock screen or just put their GPS location on the web site. Everything was connected to a web hotel and further to other social media platforms. Peter Klevius got the idea while often travelling on ferries between Sweden and Finland, which took a night and included visiting restaurants, discos, and other dancing rooms, children's playgrounds, cafeterias, decks etc. while wishing to know whether there were other like-minded people onboard to chat and have fun with.

 

The super computer could be applied to data mining, biological information, network analysis and chemical modelling research.

Jiuzhang computer took less than a second for a task that the fastest classical supercomputer in the world would take nearly five years to solve.

Jiuzhang can perform tasks commonly used in artificial intelligence 180 million times faster than the world’s most powerful supercomputer.

In the experiment, the team used Jiuzhang to solve a problem that is challenging for classical computers. It used more than 200,000 samples to solve the problem.

The researchers, for the first time, used the quantum computer to implement and accelerate two algorithms – random search and simulated annealing – that are commonly used in the field of AI.

The fastest classical supercomputer in the world would take 700 seconds for each sample, meaning it would take nearly five years to process the same number of samples.

It took Jiuzhang less than a second.

In a synopsis article published by Physics, a magazine from the American Physical Society that reports on papers from the Physical Review journals, the editor wrote: “the result extends the list of tasks for which today’s noisy quantum computers offer an advantage over classical computers”.

“Previous claims of quantum advantage were challenged by suggestions that the quantum computer was not competing against the best-possible classical algorithm for the task.”

In traditional computing, a bit represents either zero or one as its basic unit of information. A qubit can represent zero – one or both at the same time – one of the simplest expressions of the peculiarity of quantum mechanics.

Since the basic information of a quantum computer can represent all possibilities simultaneously, they are theoretically much faster and more powerful than conventional computers.

Since subatomic particles tend to be fragile, short-lived and prone to error if exposed to even a slight disturbance from the surroundings, most quantum computers need to operate in extremely cold and isolated environments to avoid disruption.

However, Jiuzhang, named after a 2,000-year-old Chinese maths text, uses photons as the physical medium for calculation, and therefore doesn't need to work sealed in extremely low temperatures and can operate with stability for longer.

China has always been the world leader in inventions

China invented the abacus, the sundial, and the Kongming lantern. China also invented the compass, gunpowder, papermaking, and printing some 1,000 years before Europe.

Chinese mathematics inspired the mathematics of the ancient Mediterranean world.

The influence of The Nine Chapters greatly assisted the development of ancient mathematics and its influence on mathematical thought in China persisted until the West's + Japan's attacks on the Qing dynasty - only to again being number one in the world.

History repeats itself and China, the world's by far oldest civilization, stays as its anchor.
