High-Resolution Dynamical Eigenspectroscopy via Variational Trotter Compression on a Superconducting Qubit Processor
Liyang Sui, Xingrui Liu, Yufan Li +10
The pursuit of high-resolution eigenspectroscopy on noisy intermediate-scale quantum devices is often hindered by the trade-off between circuit depth and coherence time. In this wo…
3D Ising criticality with Platonic lattice superconducting qubits
Liyang Sui, Hong-Hao Song, Sainan Huai +13
The three-dimensional (3D) Ising model is a foundational model in statistical physics and critical phenomena, yet its analytical intractability has long impeded the precise determi…
Electronic Band Structure of Silicon Determined via a Variational Adiabatic Eigensolver: Theory and Experiment
Xingrui Liu, Liyang Sui, Tianqi Cai +11
This work addresses the critical challenge of excited-state preparation for semiconductor band structure calculations. We introduce a variational adiabatic eigensolver (VAE) protoc…
Asymptotically Efficient Recursive Identification Under One-Bit Communications Achieving Original CRLB
Xingrui Liu, Jieming Ke, Mingjie Shao +1
This paper develops an asymptotically efficient recursive identification algorithm for autoregressive systems with exogenous inputs under one-bit communications. In particular, the…
Asymptotic Efficiency Analysis of the Recursive Least-Squares Algorithm for ARX Systems Without Projection
Xingrui Liu, Jieming Ke, Yanlong Zhao
This paper investigates the optimality analysis of the recursive least-squares (RLS) algorithm for autoregressive systems with exogenous inputs (ARX systems). A key challenge in an…
A Unified Recursive Identification Algorithm with Quantized Observations Based on Weighted Least-Squares Type Criteria
Xingrui Liu, Ying Wang, Yanlong Zhao
This paper investigates system identification problems with Gaussian inputs and quantized observations under fixed thresholds. By reinterpreting the nonlinear effects induced by qu…
Single-shot and two-shot decoding with generalized bicycle codes
Hsiang-Ku Lin, Xingrui Liu, Pak Kau Lim +1
Generalized-bicycle (GB) and more general two-block group-algebra (2BGA) quantum error-correcting codes have naturally redundant minimum-weight stabilizer generators. To use this r…
