Revealing Physical Redundancy in the Two-dimensional Fermi-Hubbard Model via Transferable Observable Reconstruction
Ao-Ning Wang, Min-Quan He, Z. D. Wang
The Fermi-Hubbard model provides a paradigmatic setting for studying strongly correlated quantum matter, where different observables are commonly used to probe charge, interaction,…
AI-enhanced Quantum Simulation of Schwinger Model
Ao-Ning Wang, Min-Quan He, Z. D. Wang
The Schwinger Model from Quantum Electrodynamics (QED) has long served as a valuable simplified model for exploring key physical phenomena in Quantum Chromodynamics (QCD)-a field r…
Public-Key Quantum Authentication and Digital Signature Schemes Based on the QMA-Complete Problem
Le-Ran Liu, Min-Quan He, Dan-Bo Zhang +1
We propose a quantum authentication and digital signature protocol whose security is founded on the Quantum Merlin Arthur~(QMA)-completeness of the consistency of local density mat…
Quantum coupon collector with mixed-state encoding
Jing-Peng Zhang, Min-Quan He, Dan-Bo Zhang
The coupon collector is a prototypical model for evaluating the number of samples for identifying a set. By superposing all elements in the set as a pure quantum state, a quantum v…
Variational Quantum Eigensolvers with Quantum Gaussian Filters for solving ground-state problems in quantum many-body systems
Yihao Liu, Min-Quan He, Z. D. Wang
We present a novel quantum algorithm for approximating the ground-state in quantum many-body systems, particularly suited for Noisy Intermediate-Scale Quantum (NISQ) devices. Our a…
