Stepping Stones to Logical Qubits

The last two years have seen an explosion of results utilizing the high connectivity afforded by neutral atom movement coupled with large qubit numbers, high fidelity 2Q gates, and mid-circuit measurement. Here I will give an overview on our most recent published results showcasing high-fidelity 2Q operations paired with mid-circuit measurement and mid-circuit atom reloading, demonstrating delayed erasure conversion, controlling logical qubits with encodings of distance-2 and distance-4, and our initial work going to higher distances with repetition codes.

Particularly, multiple examples where atom presence information is utilized in decoding or encoding strategies will be discussed. These demonstrations, and others throughout both academia and industry, are the initial stepping stones to more complicated schemes which will allow for more and more complex quantum computing over the next few years.
