At present, major countries in the world are competing fiercely in the field of quantum computers, and China has achieved important innovations in this field. Among them, the most noteworthy is China’s new round of breakthroughs in the field of quantum computing: China’s latest quantum computer “Wukong”, which will be equipped with a 72-bit superconducting quantum processor, has higher computing power than traditional computers .
This article will introduce the concept, advantages, composition, application fields of quantum computers, China’s development history and leading position in the field of quantum computing.
What is Quantum Computers?
Quantum computer is a new type of computing technology equipment. Compared with traditional computers, it has many advantages. It can complete some computing tasks that are difficult for traditional computers in a short time, such as simulating complex quantum phenomena and deciphering codes.
Advantages of Quantum Computers
Compared with traditional computers, quantum computers can complete a large number of computing tasks on the basis of interference because quantum bits (qubits) have the characteristics of superposition and entanglement. In this way, quantum computers can complete more computing tasks in a shorter period of time, and have higher computing speed and stronger computing power than traditional computers.
Specifically, quantum computers can achieve computing capabilities beyond classical computers through the two characteristics of “quantum parallelism” and “quantum entanglement”. Among them, “quantum parallelism” can handle multiple computing problems at the same time, while “quantum entanglement” can realize global computing problems, so that quantum computers can complete a large number of computing tasks in a short time.
The Development History of China's Quantum Computer
In 2017, Chinese scientist Wang Jianghong and others successfully realized quantum communication in space, which is the world’s first quantum communication experiment in space.
In 2018, China successfully released the “Micius Satellite” for Quantum Science Experiments, which open a new era of quantum communication.
In 2022, China successfully released the world’s first quantum computing prototype – “Nine Chapters” quantum computing prototype. The device has reached the world’s leading level and can perform 33-bit quantum computing. In early June 2023, the research team of the University of Science and Technology of China, based on the “Nine Chapters” optical quantum computing prototype, completed the solution to the “Dense Subgraph” and “Max-Haf” two types of graph theory problems. Compared with the world’s fastest supercomputer Exactly simulating the same experiment about 180 million times faster using current state-of-the-art classical algorithms.
In 2023, China released the latest quantum computer “Wukong”. It is equipped with a 72-bit superconducting quantum processor and is currently one of the most advanced quantum computers. It is reported that it will surpass the computing power of classical computers and has a wide range of application prospects. Its release will further promote China’s development in the field of quantum computing, and also provide better support and guarantee for China’s technological innovation on a global scale.
Superconducting Quantum Computer
Superconducting quantum computer refers to a quantum computing physical system based on superconducting Josephson junctions. There are many physical implementation schemes for quantum computing, among which superconducting quantum computing based on superconducting circuits is currently the fastest-growing and at the forefront of industrialization.
