Successfully developed the world's first quantum computer

Chinese scientists have just successfully built the world's first quantum computer, far surpassing other traditional computers, opening the way to the era of human quantum computing.

According to Business Insider, scientists at the Shanghai Institute of Advanced Science and Technology officially announced this important achievement on Wednesday. They believe that quantum computers will soon overwhelm the processing power of current supercomputers, because in theory, processing on a quantum computer is similar to reading all the books in a library at the same time, while processing on a conventional computer is similar to reading books one after another.

According to scholar Pan Jianwei - a leading quantum physicist at the Institute - quantum computing is about exploiting the fundamental principle of quantum superposition to enable parallel calculations as well as enable simulated functions at super-fast speeds.

The processing power of quantum computers also increases exponentially with the number of controllable quanta.

On a conventional silicon chip, data is represented in two states: 0 or 1. In a quantum computer, data can be in both states at the same time, thus containing much larger amounts of information.

The processing power of quantum computers also increases exponentially with the number of controllable quanta, thus being able to efficiently solve calculations on extremely large scales beyond the capabilities of current conventional computers.

Because of this huge potential of quantum computers, Europe and the US are currently actively coordinating research, in which large technology companies such as Google, Microsoft, and IBM have all shown extreme interest in research on quantum computers.

The Chinese research team is currently working on three technical issues: single photon-based systems, ultra-cold atoms, and superconducting circuits. They believe that the ability to control multi-particle entanglement is the core of quantum computing technology, and is also the focus of quantum computing research around the world. His team has now successfully studied photons in entangled states of 5, 6, 8, and 10 for the first time in the world.

It should be added that, although research has been progressing rapidly over the past two decades, building quantum computers that can actually outperform current computers in some calculations remains a major challenge.
