Quantum computing

Focus on transforming quantum science technology from laboratory prototypes into practical commercial products

Quantum computing

The world's most advanced quantum computing systems are ion traps and superconducting quantum circuits, which have focused on overall design, control, and measurement. Other quantum computing systems are still focusing on materials and processes, closer to basic physics research.

Ion trap

It is represented by 160 qubits of startup IonQ. Ion trap, also known as ion trap, is a device that captures and traps ions (ie, charged atoms or molecules) within a certain range by using electric or magnetic fields. The trapping of ions is realized in a vacuum, and the ions are not in contact with the surface of the device. The ion traps are "Paul Trap" (Quadrupole Ion Trap, Wolfgang Paul) and "Penning Trap".

Represented by IBM's 50 qubits and Google's 72 qubits, it is currently dominated by large companies, as well as startups such as Quantum Circuits and Rigetti Computing.

China is led by China University of Science and Technology and is also in the leading position in the world. In a non-impedance circuit loop, the current oscillates back and forth. The externally injected microwave signal excites the current into a superposition of quantum effects.
