Title: Neutral atom quantum computing at QuEra Computing

Quantum error correction is believed to be necessary for universal quantum computation due to its ability to correct inevitable errors. Recently, neutral atom quantum computers have demonstrated key aspects of scalable quantum error correction, such as the implementation of circuits with 48 logical qubits [1], and magic state distillation [2].

In this talk, I introduce quantum computing with neutral atoms. I will discuss neutral atom qubits, the tools that are used to control them and the implementation of gate operations and qubit movement. With these basic building blocks, I will present a neutral atom quantum computing platform based on highly parallel operations and qubit shuttling. Next, I will present QuEra Computing’s quantum computers, from the publicly accessible analog computer Aquila to our next‑generation digital systems, along with the open‑source software stack that exposes them to users. I will give a brief overview of recent demonstrations of scalable logical qubit processing in neutral atom platforms employing qubit shuttling, including implementation of logical magic state distillation. Finally, I will close with a brief overview of my path from academic research to being a scientist at QuEra.
