Ultra-bright multiplexed energy-time entangled photon generation from lithium niobate on insulator chip
Guang-Tai Xue, Yun-Fei Niu, Xiaoyue Liu +14
High-flux entangled photon source is the key resource for quantum optical study and application. Here it is realized in a lithium niobate on isolator (LNOI) chip, with 2.79*10^11 H…
Quantum-limited Localisation and Resolution in Three Dimensions
Ben Wang, Liang Xu, Lijian Zhang
As a method to extract information from optical system, imaging can be viewed as a parameter estimation problem. The fundamental precision in locating one emitter or estimating the…
Plateau dynamics with quantized oscillations of a strongly driven qubit
Yejia Chen, Zhiguo Lü, Yiying Yan +1
We present an interesting dynamical temporal localization of a strongly driven two-level system (TLS), a plateau with quantized oscillation, by an analytical and transparent method…
Mechanical dissipation below 1Hz with a cryogenic diamagnetic-levitated micro-oscillator
Yingchun Leng, Rui Li, Xi Kong +10
Ultralow dissipation plays an important role in sensing applications and exploring macroscopic quantum phenomena using micro-and nano-mechanical systems. We report a diamagnetic-le…
Single-photon scattering controlled by an imperfect cavity
Liwei Duan, Qing-Hu Chen
We study the single-photon transport in the coupled-resonator waveguide (CRW) controlled by an imperfect cavity. A Lorentzian spectrum is introduced to describe the dissipation. We…

Liwei Duan, Yan-Zhi Wang, Qing-Hu Chen
We study a non-Hermitian two-level system with square-wave modulated dissipation and coupling. Based on the Floquet theory, we achieve an effective Hamiltonian from which the bound…
Quantum verification of NP problems with single photons and linear optics
Aonan Zhang, Hao Zhan, Junjie Liao +5
Quantum computing is seeking to realize hardware-optimized algorithms for application-related computational tasks. NP (nondeterministic-polynomial-time) is a complexity class conta…
Optimal verification of stabilizer states
Ninnat Dangniam, Yun-Guang Han, Huangjun Zhu
Statistical verification of a quantum state aims to certify whether a given unknown state is close to the target state with confidence. So far, sample-optimal verification protocol…
High key rate quantum conference key agreement with unconditional security
Xiao-Yu Cao, Yu-shuo Lu, Zhao Li +3
Quantum cryptography is a major ingredient of the future quantum internet that promises various secure communication tasks. Quantum conference key agreement (CKA) is an important c…
Approaching quantum-limited metrology with imperfect detectors by using weak-value amplification
Liang Xu, Zexuan Liu, Animesh Datta +4
Weak value amplification (WVA) is a metrological protocol that amplifies ultra-small physical effects. However, the amplified outcomes necessarily occur with highly suppressed prob…
Direct Characterization of Quantum Measurements using Weak Values
Liang Xu, Huichao Xu, Tao Jiang +5
The time-symmetric formalism endows the weak measurement and its outcome, the weak value,many unique features. In particular, it allows a direct tomography of quantum states withou…
Verification of phased Dicke states
Zihao Li, Yun-Guang Han, Hao-Feng Sun +2
Dicke states are typical examples of quantum states with genuine multipartite entanglement. They are valuable resources in many quantum information processing tasks, including mult…
