Breaking the Multiplicative Overhead in Quantum Entropy Estimation
Junxiang Huang, Chenyang Li, Lu-Fan Zhang +2
The von Neumann, Tsallis, and Rényi entropies are fundamental measures of quantum information. A common estimation strategy multiplies the worst-case costs of spectral transformati…
Low-cost algorithm-to-execution framework for surface-code quantum computing
Yunxin Tang, Zixuan Huo, Junxiang Huang +14
Fault-tolerant quantum computing is progressing from demonstrations of individual logical components toward the execution of useful quantum algorithms on large-scale error-correcte…
Generalized Mermin Inequalities for Benchmarking Large-Scale GHZ States
Jianbin Cai, Junxiang Huang, Fynn Otto +15
Multipartite Bell tests provide a correlation-only route to benchmarking quantum processors, but their application at large scales is hindered by the rapid decay of many-body corre…
Quantum-classical crossover in fault-tolerant quantum dynamics simulation
Jinzhao Sun, Bozhen Zhou, Jue Xu +28
While quantum computers promise to solve classically intractable problems, identifying the point at which fault-tolerant quantum computation outperforms the best classical algorith…
Streaming the partial-transpose moment hierarchy with order-independent quantum memory
Junxiang Huang, Xiaoyang Wang, Xiao Yuan +1
Partial transposition reveals mixed-state entanglement through the spectrum of , but this operator is not generally a physical state. Its power moments are accessible…
A Review of Variational Quantum Algorithms: Insights into Fault-Tolerant Quantum Computing
Zhirao Wang, Junxiang Huang, Runyu Ye +8
Variational quantum algorithms (VQAs) have established themselves as a central computational paradigm in the Noisy Intermediate-Scale Quantum (NISQ) era. By coupling parameterized…
Estimating Local Observables via Cluster-Level Light-Cone Decomposition
Junxiang Huang, Yunxin Tang, Xiao Yuan
Simulating large quantum circuits on hardware with limited qubit counts is often attempted through methods like circuit knitting, which typically incur sample costs that grow expon…
Obtaining Accurate Ground-State Properties on Near-term Quantum Devices
Qi-Ming Ding, Jiawei Peng, Junxiang Huang +6
Accurate ground-state calculations on noisy quantum computers are fundamentally limited by restricted ansatz expressivity and unavoidable hardware errors. We introduce a hybrid-qua…
One- and two-dimensional cluster states for topological phase simulation and measurement-based quantum computation
Tao Jiang, Jianbin Cai, Junxiang Huang +152
Quantum entanglement is a fundamental resource for quantum information processing and serves as a critical benchmark for quantum hardware performance. Cluster states are a special…
