Quantum-Enhanced Dark Matter Search Using Cat States
Pan Zheng, Yanyan Cai, Bin Xu +12
Quantum metrology has recently emerged as a powerful approach for dark matter (DM) searches, particularly using nonclassical bosonic states in microwave cavities that are sensitive…
Experimental observation of exact quantum critical states
Wenhui Huang, Xin-Chi Zhou, Libo Zhang +29
Anderson localization physics features three fundamental types of eigenstates: extended, localized, and critical, with the third one exhibiting the exotic properties in-between the…
Distributed multi-parameter quantum metrology with a superconducting quantum network
Jiajian Zhang, Lingna Wang, Yong-Ju Hai +19
Quantum metrology has emerged as a powerful tool for timekeeping, field sensing, and precision measurements in fundamental physics. With the advent of distributed quantum metrology…
Quantum dynamics of microwave photons in synthetic frequency dimension
Zheshu Xie, Luojia Wang, Jiawei Qiu +13
Synthetic frequency dimension offers a powerful approach to simulate lattice models and control photon dynamics. However, extending this concept into the quantum regime, particular…
Quantum-enhanced metrology with large Fock states
Xiaowei Deng, Sai Li, Zi-Jie Chen +11
Quantum metrology uses non-classical states, such as Fock states with a specific number of photons, to achieve an advantage over classical sensing methods. Typically, quantum metro…
Logical operations with a dynamical qubit in Floquet-Bacon-Shor code
Xuandong Sun, Longcheng Li, Zhiyi Wu +29
Quantum error correction (QEC) protects quantum systems against inevitable noises and control inaccuracies, providing a pathway towards fault-tolerant (FT) quantum computation. Sta…
