Efficient adaptive control strategy for multi-parameter quantum metrology in two-dimensional systems
Qifei Wei, Shengshi Pang
Quantum metrology leverages quantum resources such as entanglement and squeezing to enhance parameter estimation precision beyond classical limits. While optimal quantum control st…
Floquet Diamond Sensor with Optimal Precision
Qi-Tao Duan, Teng Li, Si-Qi Chen +2
The diamond sensor has emerged as a promising platform for quantum sensing, enabling the estimation of physical quantities -- such as microwave~(MW) field -- with precision unattai…
Optimal quantum superresolution for full distance between incoherent optical sources in two dimensions
Junyan Li, Shengshi Pang
The Rayleigh criterion has long served as a fundamental limit for the resolution of optical imaging. Recent advances in multiparameter quantum metrology have led to quantum superre…
Two measurement bases are asymptotically informationally complete for any pure state tomography
Tianfeng Feng, Tianqi Xiao, Yu Wang +6
One of the fundamental questions in quantum information theory is to find how many measurement bases are required to obtain the full information of a quantum state. While a minimum…
