Quantum light source with lithium tantalate for scalable photonic quantum circuits
Yun-Ru Fan, Bo-Wen Chen, Dan Xu +13
Thin-film lithium tantalate (TFLT) has emerged as a promising integrated photonic platform owing to its low photorefractive noise, high optical damage threshold, and reduced birefr…
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…
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…
