Metrological Sensitivity beyond Gaussian Limits with Cubic Phase States
Jiajie Guo, Shuheng Liu, Boxuan Jing +2
Cubic phase states provide the essential non-Gaussian resource for continuous-variable quantum computing. We show that they also offer significant potential for quantum metrology,…
Characterizing the Multipartite Entanglement Structure of Non-Gaussian Continuous-Variable States with a Single Evolution Operator
Mingsheng Tian, Xiaoting Gao, Boxuan Jing +4
Multipartite entanglement is an essential resource for quantum information tasks, but characterizing entanglement structures in continuous variable systems remains challenging, esp…
Task-Oriented Gaussian Optimization for Non-Gaussian Resources in Continuous-Variable Quantum Computation
Boxuan Jing, Feng-Xiao Sun, Qiongyi He
In continuous-variable systems, non-Gaussian resources are essential for achieving universal quantum computation that lies beyond classical simulation. Among the candidate states,…
Graphical Framework for Non-Gaussian Quantum States
Lina Vandré, Boxuan Jing, Yu Xiang +2
We provide a graphical method to describe and analyze non-Gaussian quantum states using a hypergraph framework. These states are pivotal resources for quantum computing, communicat…
