Towards fault-tolerant quantum computing with neutral atoms

Monday, 7th of September, 9:30-10:15, room CTE 1

Neutral-atom platforms have emerged as a leading platform for digital quantum simulations and quantum computing, with present-day systems surpassing a thousand qubits and achieving gate fidelities near the 99.9% level. As the field transitions toward scalable, fault-tolerant quantum computing, robust quantum error correction becomes increasingly important. In this talk, I will describe recent work at the University of Strasbourg developing architectures for efficient quantum error correction tailored to Rydberg-atom arrays. I will present new ideas and codes for performing error correction, highlighting conditions under which the latter offer advantages over conventional schemes. One example is low-density parity-check codes that can encode more information and protect better from physical errors with respect to conventional surface codes. Both challenges and new ideas for performing error-corrected logical quantum computation within this framework are discussed.
