Optimal Shadow Estimation with Minimal Measurement Settings
Zhiyao Yang, Datong Chen, Huangjun Zhu
Shadow estimation is a powerful framework for predicting quantum properties from randomized measurements. While -design protocols achieve optimal worst-case performance, the min…
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-…
High-Precision Fidelity Estimation with Common Randomized Measurements
Zhongyi Yang, Datong Chen, Zihao Li +1
Efficient fidelity estimation of multiqubit quantum states is crucial to many applications in quantum information processing. However, to estimate the infidelity with multiplic…
Optimal Quantum Measurements with respect to the Fidelity
Datong Chen, Huangjun Zhu
Fidelity is the standard measure for quantifying the similarity between two quantum states. It is equal to the square of the minimum Bhattacharyya coefficient between the probabili…
Nonstabilizerness Enhances Thrifty Shadow Estimation
Datong Chen, Huangjun Zhu
Shadow estimation is a powerful approach for estimating the expectation values of many observables. Thrifty shadow estimation is a simple variant that is proposed to reduce the exp…
Suppressing classical noise in the accelerated geometric phase gate by optimized dynamical decoupling
Da-tong Chen, Jun Jing
In the quantum-computation scenario, geometric phase-gates are becoming increasingly attractive for their intrinsic fault tolerance to disturbance. With an adiabatic cyclic evoluti…
