Quantum Nonlinear Properties from a Single Measurement Setting
Zihao Li, Datong Chen, Dayue Qin +2
Nonlinear properties of quantum states are essential to quantum information and many-body physics, but assessing them experimentally is challenging, as it typically requires multi-…
Phase shadow: A noise-tolerant path to global quantum property estimation
Qingyue Zhang, Dayue Qin, Zhou You +3
Measuring global quantum properties-such as the fidelity to complex multipartite states-is both an essential and experimentally challenging task. Classical shadow estimation offers…
Nearly query-optimal classical shadow estimation of unitary channels
Zihao Li, Changhao Yi, You Zhou +1
Classical shadow estimation (CSE) is a powerful tool for learning the properties of quantum states and quantum processes. Here we consider the CSE task for quantum unitary channels…
Auxiliary-Free Replica Shadows: Efficient Estimation of Multiple Nonlinear Quantum Properties
Qing Liu, Zihao Li, Xiao Yuan +2
Efficient estimation of nonlinear properties is a significant yet challenging task from quantum information processing to many-body physics. Current methodologies often suffer from…
