Green quantum computing in the sky

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.
