A Calibrated Test of Internal Action Maps: State Signals Without Global Affine Closure
Dekun Yang
A hidden state signal can be decodable or causally usable without supporting a reusable action map. We test whether action maps fitted without a source reach its natural post-actio…
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…
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…
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…
