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…
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…
