Chinese Scientists Control Quantum Decoherence with New Breakthrough

2/20/2026

Summary

Story summary

Chinese scientists directly observed and manipulated prethermalisation using the 78-qubit Chuang-tzu 2.0 superconducting processor.
This achievement enables control over the speed of quantum decoherence, addressing challenges in maintaining information integrity in quantum computing.
The study, published in Nature, reveals a new, stable, and controllable intermediate stage during quantum evolution, which could help preserve quantum information.
The work was conducted by the Institute of Physics at the Chinese Academy of Sciences.
