Who can find better quantum materials and build a better quantum computer, who can take the opportunity in the fourth industrial revolution

Ding Hong

Classic computers take 100 years to decipher the password, and quantum computers can break through in 1 second. It is seeing that this "flood power" has become one of the cutting -edge science and technology fields in the world's key development of countries in the world.

Yesterday afternoon, the Shanghai Popular Sciences Forum invited Ding Hong, a professor at the Li Zhengdao Research Institute of Shanghai Jiaotong University, Ding Hongzuo's "Quantum Calculation -the Fourth Industrial Revolutionary Engine" theme report to introduce the concepts, advantages and development channels for quantum computing.

In July of this year, Israel announced the establishment of a $ 29 million quantum computing research and development center, and in October 2021, Chinese scientists brought "Zu Chongzhi No. 2" and "Nine Chapter 2" quantum computers. The probability of quantum computing will become one of the engines of the fourth industrial revolution. Who can find better quantum materials, build better quantum devices, and build better quantum computers, who can take advantage of this revolution. machine.

Quantum physics seems to be high -cold, but has already entered our lives, such as mobile phones, computers and other electronic devices involving the principles of quantum physics. "Atoms, photons, and electrons are quantums." Ding Hong said that quantum is the basic unit for constituting substances and the most basic carrier of energy. Quantum superposition and quantum entanglement are where quantum physics is different from classic physics.

What is quantum superposition? Ding Hong gave an example. In the classic physics, from a macro perspective, the "attitude" of any material is certain. For example, put a book on the table, either front or opposite. However, in the quantum world, books can be positive or opposite, becoming an uncertain stack.

In the field of scientific and technological innovation, quantum computing can not only be applied to the field of artificial intelligence, improve machine learning efficiency, but also cope with complex situations, such as accurate predictions of weather. Many inconveniences in life, such as traffic congestion, can also rely on its rapid algorithm solution.

Ding Hong said that the development of quantum computing is very fast. In the past, it was generally believed that quantum computers could only be achieved after 30 or 50 years. According to the current development speed, it may become a reality after 5-10 years.

The event was co -sponsored by the Shanghai Science and Technology Museum, the Li Zhengdao Research Institute of Shanghai Jiaotong University, and the Shanghai Science Popular Education Development Foundation. The Shanghai Science Popularization forum has been held for 183 games, and 375 scientists at home and abroad have been invited to give a wonderful speech.
