Enhancement of sensitivity near exceptional points in dissipative qubit-resonator systems
Pei-Rong Han, Fan Wu, Xin-Jie Huang +11
Dissipation usually plays a negative role in quantum metrological technologies, which aim to improve measurement precision by leveraging quantum effects that are vulnerable to envi…
Properties and Application of Gaussian Quantum Processes
Mengzhen Zhang
Gaussian states, operations, and measurements are central building blocks for continuous-variable quantum information processing which paves the way for abundant applications, espe…
Interference-based universal decoupling and swapping for multimode bosonic systems
Mengzhen Zhang, Shoumik Chowdhury, Liang Jiang
Beam-splitter operations are widely used to process information encoded in bosonic modes. In hybrid quantum systems, however, it might be challenging to implement a reliable beam-s…
Path-Independent Quantum Gates with Noisy Ancilla
Wen-Long Ma, Mengzhen Zhang, Yat Wong +5
Ancilla systems are often indispensable to universal control of a nearly isolated quantum system. However, ancilla systems are typically more vulnerable to environmental noise, whi…
Heralded Generation and Detection of Entangled Microwave--Optical Photon Pairs
Changchun Zhong, Zhixin Wang, Changling Zou +8
Quantum state transfer between microwave and optical frequencies is essential for connecting superconducting quantum circuits to coherent optical systems and extending microwave qu…
Quantum Noise Theory of Exceptional Point Sensors
Mengzhen Zhang, William Sweeney, Chia Wei Hsu +3
Distinct from closed quantum systems, non-Hermitian system can have exceptional points (EPs) where both eigenvalues and eigenvectors coalesce. Recently, it has been proposed and de…
