Improving precision scaling via backaction-evading continuous measurement in a driven-dissipative Kerr parametric oscillator
Cheng Zhang, Xinhui Cui, Jiaying Pan +3
Dissipative phase transitions in the driven-dissipative Kerr parametric oscillator offer a promising route for realizing criticality-enhanced quantum sensing based on continuous me…
Criticality-enhanced global frequency sensing with a monitored Kerr parametric oscillator via extended Kalman filter
Cheng Zhang, Mauro Cirio, Xin-Qi Li +1
We analyze a global sensing scenario in which the frequency of a monitored Kerr parametric oscillator is estimated assuming limited prior information. The frequency is estimated in…
Enhancing information retrieval in quantum-optical critical systems via quantum measurement backaction
Cheng Zhang, Mauro Cirio, Xin-Qi Li +1
Continuous monitoring of open quantum-optical systems offers a promising route towards quantum-enhanced estimation precision. In such continuous-measurement-based sensing protocols…
Purified pseudomode model for nonlinear system-bath interactions
Cheng Zhang, Neill Lambert, Xin-Qi Li +2
The theory of purified pseudomodes [arXiv:2412.04264 (2024)] was recently developed to provide a numerical tool for the analysis of the properties of a quantum system and the envir…
A purified input-output pseudomode model for structured open quantum systems
Pengfei Liang, Neill Lambert, Si Luo +2
A full understanding of open quantum systems requires the characterization of both system and environmental properties. However, the complexity of the environmental statistics in t…
Super-bath Quantum Eigensolver
Tianren Wang, Zongkang Zhang, Bing-Nan Lu +2
The simulation of the dynamics of a system coupled to a low-temperature environment is a promising application of quantum computers to determine ground-state properties of physical…
