COSC Held a Lecture on New Quantum Revolution

Date: 2017-09-04


COSC invited Professor Chen Yu’ao from the University of Science and Technology of China to give a lecture on “new quantum revolution”. COSC Chairman Wang Zhongwei attended and chaired the event. COSC Vice Chairman Wang Weimin, Vice Chairwoman Wang Hong, Vice Chairman Zhao Bing and some counsellors and research fellows attended the lecture.

Wang Zhongwei said that China has made important progress in quantum communications in the past few years, which has received a lot of attention worldwide and extensive media coverage at home. The lecture will provide inspirations and benefits for making policy advice.

The Mysterious Quantum World


As Professor Chen said, human beings are at the threshold of the next-generation quantum revolution. A new quantum revolution is in the making. Major economies in the world are competing intensely in quantum communications and quantum computing.

What is quantum? Quantum is the most basic element making up matters. It is the most basic carrier of energy. It is an indivisible unit of energy. What is amazing about quantum is its unique property: quantum superposition and quantum entanglement.

The Second Quantum Revolution
Professor Chen said that information science was developed in the 20th century when people was studying and applying quantum mechanics and the theory of relativity, which taken human civilization a giant step forward. The first quantum revolution gave rise to nuclear bomb, laser, transistor, nuclear magnetic resonance, the first-generation computer, the Internet and GPS. The second quantum revolution brought about applications such as quantum communication and quantum computing.

Quantum teleportation is an unconditional, secure way of communication. Quantum superposition leads to a direct conclusion: an unknown quantum cannot be replicated accurately. Quantum information technology is the earliest information application based on quantum superposition. The indivisibility of single photon and the non-replicability of quantum ensure against eavesdropping and breaching.

Intense International Competition
Chen believes that the competition in quantum technology will be intense in the coming 10 to 15 years. Globally, there is a trend of transition from government dominance to the participation of tech giants. China now stands at the forefront in quantum technology.       

What does the future hold? Chen believed that the first quantum revolution exerted a huge impact on human society and the way of life. The second quantum revolution represented by quantum information technology will certainly lead to big strides in human civilization. It will also provide tremendous opportunities for a China as it makes the transition from a follower to a leader in information technology.
Chen also quoted the Wall Street Journal by saying that “China is back to the forefront of innovation after 1,000 years.”

At the end of the lecture, COSC counsellors and research fellows had in-depth exchanges with Professor Chen on quantum observation, quantum computer, quantum technology and energy saving and emission reduction, quantum technology, carbon sequestration.
