Arrays of Atoms and Spins: Quantum Technologies that Sense, Compute and Scale

Quantum technologies are moving from promise to prototypes that can compute, simulate, sense, and communicate in new ways. In this talk, I’ll give a tour of two optically interfaced quantum platforms that bring these ideas within reach. First, I'll discuss systems based on the nitrogen-vacancy center in diamond, a solid-state platform within which we detect and control tens of individual nuclear spins for nanoscale quantum sensing, simulation, and computation. Second, I'll discuss assembled arrays of neutral atoms in optical tweezers that enable large, programmable processors. I’ll introduce a novel architecture that enables continuous operation of more than 3,000 coherent qubits and explain why this matters for quantum error correction and scaling. I’ll close with opportunities and open questions.
