Abstract

The cryogenic cooling requirements of quantum computing pose significant challenges to sustainable deployment. We propose deploying quantum processors on stratospheric High Altitude Platforms (HAPs), leveraging −50 °C ambient temperatures to reduce cooling demands by 21%. Our analysis demonstrates that quantum-enabled HAPs support 30% more qubits than terrestrial quantum data centers while maintaining superior reliability, especially when leveraging advanced hardware capabilities. By leveraging strategic atmospheric positioning, this solar-powered solution enables sustainable, high-performance quantum computing.
