Global Parametric Gates for Multi-qubit Entanglement
Jize Yang, Lin Guo, Haonan Xiong +8
We propose and experimentally demonstrate a global parametric gate that generates multi-qubit entangled states in a single step. By applying a parametric drive to a common qubit at…

Scalable Low-overhead Superconducting Non-local Coupler with Exponentially Enhanced Connectivity
Haonan Xiong, Jiahui Wang, Juan Song +8
Quantum error correction codes with non-local connections such as quantum low-density parity-check (qLDPC) incur lower overhead and outperform surface codes on large-scale devices.…

Performance Analysis for Crosstalk Errors between Parallel Entangling Gates in Trapped Ion Quantum Error Correction
Fangxuan Liu, Gaoxiang Tang, Luming Duan +1
The ability to execute a large number of quantum gates in parallel is a fundamental requirement for quantum error correction, allowing an error threshold to exist under the finite…
