Quantum-computing reliability for HAP platforms

Determine how to address radiation, quantum-link loss, payload reliability, and error-correction requirements for quantum-computing-enabled high-altitude platforms and multi-HAP quantum-computing systems.

Background

The paper discusses placing cryogenic quantum processors on solar-powered HAPs and connecting them through free-space optical links and low-altitude repeaters. Although the cited study reports energy and qubit-capacity benefits at stratospheric altitude, scaling such systems across multiple HAPs introduces unresolved engineering constraints involving radiation exposure, quantum-link losses, payload dependability, and error correction.

Multi-HAP cooperation improves scalability, although radiation, quantum-link loss, payload reliability, and error correction remain open issues.
