Robust Mølmer-Sørensen Gate Against Symmetric and Asymmetric Errors
Wenhao Zhang, Gaoxiang Tang, Kecheng Liu +4
To achieve the entangling gate fidelity above the quantum error correction threshold, it is critical to suppress errors due to experimental imperfection. We consider the Mølmer-Sør…

Scaling of entangling-gate errors in large ion crystals
Wenhao He, Wenhao Zhang, Xiao Yuan +2
Trapped-ion has shown great advantages in building quantum computers. While high fidelity entangling-gate has been realized for few ions, how to maintain the high fidelity for larg…
