Scaling Enhancement in Quantum Metrology via Indefinite-Time-Direction Encoding
Binke Xia, Jingzheng Huang, Yuxiang Yang +1
The precision limit in quantum metrology, quantified by the root-mean-square error of parameter estimation, is conventionally expected to improve at most linearly with the total in…
Resource quantification for programming low-depth quantum circuits
Entong He, Yuxiang Yang
Noisy intermediate-scale quantum (NISQ) devices pave the way for implementing quantum algorithms that offer quantum advantages over their classical counterparts. Due to the intrins…
Nonlinear Enhancement of Measurement Precision via a Hybrid Quantum Switch
Lei Chen, Yu-Xiang Yang, Gong-Chu Li +8
Quantum metrology promises measurement precision beyond the classical limit by using suitably tailored quantum states and detection strategies. However, scaling up this advantage i…
Optimal quantum metrology under energy constraints
Longyun Chen, Yuxiang Yang
The traditional framework of quantum metrology commonly assumes unlimited access to resources, overlooking resource constraints in realistic scenarios. As such, the optimal strateg…
