The conference will convene experts in high-energy physics, quantum computing, error correction, and quantum hardware to assess the opportunities and challenges at the transition from NISQ devices to fault-tolerant and error-corrected quantum technologies. Scientifically compelling HEP targets will be assessed, including real-time dynamics, scattering, confinement, and non-equilibrium phenomena, that are classically hard and may ultimately benefit from quantum advantage. The conference will be a forum for lively discussions on the current status of quantum simulations of fundamental systems, the resource requirements for meaningful HEP observables, and the integration of quantum error-correction strategies into realistic computational pipelines. Particular emphasis will be placed on benchmark problems, uncertainty quantification, verification beyond classical simulation, and co-design across applications, algorithms, and hardware platforms. This conference is intended to foster new collaborations among theorists, quantum information scientists, and experimental and industrial leaders, and to clarify the near-term and long-term paths toward useful quantum computing for high-energy physics.
