(Yicai) July 19 -- Quantum computing is on a development growth curve similar to artificial intelligence in its earliest stages, but there must be caution against unrealistic bubbles, according to the executive dean of the University of Science and Technology's Shanghai institute for advanced studies.

Quantum computers are a new tool, similar to others in their role in scientific development, and they can significantly boost scientific progress, Lu Chaoyang recently said.

Quantum computing is a new computing paradigm that performs calculations by manipulating qubits based on the principles of quantum mechanics. Unlike traditional computers, quantum computers possess an exponential advantage in computational power.

"With the nation's support, we hope to use quantum computers for quantum simulations in the future, exploring physical phenomena that are difficult to simulate with traditional methods to gain a deeper understanding," Lu noted.  

Quantum computing has moved beyond the first development stage of proof-of-concept and entered the second stage, involving solving problems beyond the reach of existing knowledge frameworks and computational power, thereby achieving "quantum supremacy," Lu pointed out.

Although hundreds of teams worldwide are researching quantum computing, only a few have truly entered the second stage, surpassing classical computers in solving specific problems, Lu said. "After achieving the second stage, we hope to explore small-scale quantum computing and hope it will have practical value even at this scale."

In 2019, Google's AI division created Sycamore, a transmon superconducting quantum processor with 53 qubits, achieving "quantum supremacy" for the first time. China has since produced leading quantum computers, including Jiuzhang and Zu Chongzhi, to become the second country to reach quantum supremacy.
