Quantum Algorithms in the Fault Tolerant Era
Organizers: Michael Beverland (IBM Quantum), Matt Amy (SFU, Vancouver), Christian Bauer (LBNL), Krysta Svore (NVIDIA), Nathan Wiebe (University of Toronto)

Quantum circuits for the most promising applications, including fundamental science, material design and chemistry, will likely exceed the limits of NISQ hardware due to noise. Fault-tolerance schemes enable reliable execution on encoded qubits but impose scheme-specific constraints on the operations available to a circuit. An ambitious goal is to both (1) design algorithms and circuits that efficiently exploit the fault-tolerant operations of a given scheme, and (2) design fault-tolerance schemes that enhance the computational power of the circuits they support. This is challenging, in part because the fields of fault tolerance, quantum algorithms and quantum circuit compilation are rapidly evolving and largely pursued by separate research communities. This workshop aims to foster tighter collaboration between these areas and with near-term quantum simulations.
The workshop is designed to be collaborative rather than conference-style. We expect to have one introductory 60-minute talk on most mornings, aimed at establishing shared background and bringing participants from different areas into the same conversation. Most of each day will be reserved for discussion, collaboration, and work on concrete open problems. Shorter talks, discussion sessions, and problem-focused working groups may be added as the program develops.
