BOSTON, PARIS, March 11, 2026 -- Alice & Bob, a leader in fault-tolerant quantum computing, will present more than a dozen research talks at the APS Global Physics Summit, demonstrating new advances in its cat-qubit architecture – a hardware-efficient approach designed to reduce the number of qubits required for fault-tolerant quantum computers.

The presentations span several key challenges in scaling quantum computers, including stabilizing cat qubits, extending their intrinsic error protection, and enabling core components of fault-tolerant computation such as high-fidelity magic-state preparation.

Researchers will also introduce new techniques to simulate large superconducting quantum systems and to validate the ultra-low logical error rates required for practical quantum computing.

Together, the results highlight progress across the full stack required to build scalable fault-tolerant quantum computers, from device physics and circuit design to quantum error correction and system verification.

The APS Global Physics Summit held March 15-20 in Denver, Colorado, brings together thousands of physicists from around the world to present new developments across all disciplines of physics, including quantum mechanics.
