Optimal Strategies for Multi-parameter Quantum Metrology
Linxuan Li, Zihao Hu, Longyun Chen +2
Estimating multiple unknown parameters simultaneously is essential for practical quantum sensing. However, it faces a fundamental challenge: the optimal strategy for estimating one…
Resource quantification for programming low-depth quantum circuits
Entong He, Yuxiang Yang
The paper analyzes the resources needed to program low‑depth brickwork quantum circuits on NISQ devices, establishing a worst‑case program cost of Θ(N polylog N) and examining trad…
Optimal classical shadow estimation of unitary channels at Heisenberg limit
Entong He, Zihao Li, Noam Scully +2
Full tomography of an unknown quantum evolution is resource-intensive and often unnecessary when the goal is only to predict selected properties. This motivates the study of classi…
Scaling-optimal purification of noisy qubit unitary channels
Ryotaro Niwa, Satoshi Yoshida, Koki Ono +5
We consider the problem of purifying noisy qubit unitary channels. Given the ability to apply an unknown qubit unitary channel followed by depolarizing noise, we aim to construct a…
A Voxel-Based Quantum Computing Method (VBQC) for Solid Mechanics Problem
Feng Wu, Yuxiang Yang, Li Zhu +3
Quantum computing presents a promising method to overcome the efficiency and memory constraints in large-scale mechanical problems, with numerous successful applications demonstrat…
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-…
