Ultrahigh threshold nonstabilizer nonlinear quantum error correcting code

Maga Grafe, Kaixuan Zhou, Zaman Tekin +5

We introduce a novel type of quantum error correcting code, called the spinor code, based on spaces defined by total spin. The code is a nonstabilizer code, and is also a nonlinear…

Neutral atom entangling gate in the ultrastrong coupling regime

Ebubechukwu O. Ilo-Okeke, Tongzhou Wang, Valentin Ivannikov +1

We propose a method to deterministically entangle qubits or ensembles of qubits interacting with a shared bosonic mode in the ultrastrong coupling regime. We show that the resultin…
