Engineered Randomness for Ubiquitous Quantum-Enhanced Metrology in Exponential-Dimensional Manifolds
Yaoming Chu, Baiyi Yu, Hartmut Häffner +3
The exponential growth of many-body Hilbert space presents a fundamental barrier to quantum technology, obscuring the search for physically significant states within an astronomica…
Overcoming frequency resolution limits using a solid-state spin quantum sensor
Qingyun Cao, Genko T. Genov, Yaoming Chu +4
The ability to determine precisely the separation of two frequencies is fundamental to spectroscopy, yet the resolution limit poses a critical challenge: distinguishing two incoher…
Quantum metrological capability as a probe for quantum phase transition
Xiangbei Li, Yaoming Chu, Shaoliang Zhang +1
The comprehension of quantum phase transitions (QPTs) is considered as a critical foothold in the field of many-body physics. Developing protocols to effectively identify and under…
Non-Hermitian sensing in the absence of exceptional points
Lei Xiao, Yaoming Chu, Quan Lin +4
Open systems possess unique potentials in high-precision sensing, yet the majority of previous studies rely on the spectral singularities known as exceptional points. Here we theor…
Quantum delocalization on correlation landscape: The key to exponentially fast multipartite entanglement generation
Yaoming Chu, Xiangbei Li, Jianming Cai
Entanglement, a hallmark of quantum mechanics, is a vital resource for quantum technologies. Generating highly entangled multipartite states is a key goal in current quantum experi…
