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…
Depletion-mode N-polar AlN-based high electron mobility transistors with improved on/off ratios
Xu Yang, Sheng Zhang, Ke Wei +4
We report N-polar AlN-based high-electron mobility transistors (HEMTs) with a GaN channel thickness of 5.2 nm on N-polar AlN on sapphire. The threshold voltage is around -2.4 to -3…
Breaking the scalability barrier via a vertical tunable coupler in 3D integrated transmon system
Xudong Liao, Shuyi Pan, Zhenxing Zhang +11
Scaling superconducting quantum processors beyond the constraints of monolithic planar architectures is essential for fault-tolerant quantum computation. Here we demonstrate a thre…
Lindbladian Simulation with Commutator Bounds
Xinzhao Wang, Shuo Zhou, Xiaoyang Wang +3
Trotter decomposition provides a simple approach to simulating open quantum systems by decomposing the Lindbladian into a sum of individual terms. While it is established that Trot…
Multiplexed double-transmon coupler scheme in scalable superconducting quantum processor
Tianqi Cai, Chitong Chen, Kunliang Bu +7
Precise control of superconducting qubits is essential for advancing both quantum simulation and quantum error correction. Recently, transmon qubit systems employing the single-tra…
