## China NEWS AND UPDATES



- [Chinese Scientists Report New Quantum Light Source is a Step Toward More Efficient Quantum Chips](/quantum-news/2024/chinese-scientists-report-new-quantum-light-source-is-a-step-toward-more-efficient-quantum-chips.md)

  Chinese researchers have developed a quantum light source using gallium nitride (GaN), a semiconductor commonly used in blue LEDs. This innovation marks progress toward functional quantum chips by generating entangled light particles essential for quantum systems. The GaN-based device offers a wider wavelength range than existing sources, promising more efficient, easily integrated quantum chips for computing and other applications. Researchers foresee GaN enabling all-on-chip quantum photonic circuits.

  A Chinese company has made a 72-qubit superconducting quantum chip with foreign machines as the United States’s curbs failed to slow China’s development in this area. Origin Quantum, a Hefei-based quantum computer maker, on January 6 officially launched its third-generation quantum computer called Wukong, which uses the name of the Monkey King in Chinese mythology as the superhero can transform into 72 different forms.
