Quantum delocalization on correlation landscape: The key to exponentially fast multipartite entanglement generation Yaoming Chu, Xiangbei Li, Jianming Cai, arXiv :2404.10973 (2024)

Entanglement distinctively sets the quantum world apart from its classical counterpart. Many-particle entangled quantum states are created in an exponentially fast speed through a novel physical picture of quantum delocalization on a correlation landscape, the latter is defined in a minimal operator subspace.

Non-Hermitian sensing in the absence of exceptional points Lei Xiao, Yaoming Chu, Quan Lin, Haiqing Lin, Wei Yi, Jianming Cai, Peng Xue, arXiv:2403.08218(2024)

We confirm the basic mechanism by simulating the sensor-field dynamics using photon interferometry, and, as a concrete example, demonstrate the enhanced sensing of signals encoded in the setting angle of a wave plate. More

Identifying possible mechanism for quantum needle in chemical magnetoreception Xiaoyu Chen, Haibin Liu, Jianming Cai, arXiv:2401.17323 (2024)

A new type of quantum needle model system can relax the requirement for radical pair lifetime by an order of magnitude, and retains a narrow functional window around the geomagnetic field. This provides evidence for identifying the possible physical mechanism for quantum needle in chemical compass model of avian magnetoreception. More

Protecting Quantum Information via Destructive Interference of Correlated Noise Alon Salhov, Qingyun Cao, Jianming Cai, Alex Retzker, Fedor Jelezko, Genko Genov, arXiv :2312.02267(2023)

We achieve a tenfold coherence time extension by destructive interference of cross-correlated noise, improve control fidelity, and surpass the state-of-the-art sensitivity for high frequency quantum sensing, significantly expanding the applicability of noise protection strategies. More
