# Breakthrough in quantum computing
This year, China achieved a quantum computational advantage in two mainstream technical routes: one via photonics quantum computing technology and the other via superconducting quantum computing technology.
Led by renowned Chinese quantum physicist Pan Jianwei, the research team designed a 66-qubit programmable superconducting quantum computing system named Zuchongzhi 2.1.
The readout fidelity of Zuchongzhi 2.1 was considerably improved to an average of 97.74%.
Pan's team also announced the Jiuzhang 2.0, another quantum computer based on light, which can carry out large-scale Gaussian boson sampling septillion times faster than the world's fastest existing supercomputer.
