Title: “Architecting a neutral atom quantum computer: the cost of connectivity”

Abstract: Progress in quantum computing with neutral atom qubits has advanced rapidly with the development of large 2D arrays and high fidelity entangling gates and qubit measurements. As with all qubit platforms the challenge of establishing rapid connectivity between large numbers of qubits must be overcome for scalable computation. Neutral atoms can be entangled at short length scales via Rydberg interactions, at medium length scales with physical transport,  and at long scales via photons. I will discuss these options, including recent progress towards remote entanglement with multiple atomic species.
