Author(s): Xinyue Long, Xiaodong Yang, Xiangyu Wang, Yufang Feng, Carlos H. S. Vieira, Ran Liu, Xinfang Nie, Jun Li, and Dawei Lu Quantum metrology promises to surpass classical precision limits by leveraging quantum resources such as entanglement. Maximally entangled Greenberger-Horne-Zeilinger (GHZ) states are theoretically optimal probes for quantum metrology. However, they are fragile to environmental noise, severely limit… [Phys. Rev.
