Non-commutativity as a Universal Characterization for Enhanced Quantum Metrology
Ningxin Kong, Haojie Wang, Mingsheng Tian +4
A central challenge in quantum metrology is to effectively harness quantum resources to surpass classical precision bounds. Although recent studies suggest that the indefinite caus…
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…
Experimental Verification of Entangled States in the Adversarial Scenario
Wen-Hao Zhang, Zihao Li, Gong-Chu Li +5
Efficient verification of entangled states is crucial to many applications in quantum information processing. However, the effectiveness of standard quantum state verification (QSV…
Surpassing the Global Heisenberg Limit Using a High-effciency Quantum Switch
Yu Guo, Yuehan Chen, Geng Chen +5
Indefinite causal orders have been shown to enable a precision of inverse square N in quantum parameter estimation, where N is the number of independent processes probed in an expe…
