Computing system with superconducting and non-superconducting components located on a common substrate

A computing system including a common substrate having both superconducting components and non-superconducting components is provided. The superconducting components may be attached towards a first end of the common substrate and the non-superconducting components may be attached towards a second end, opposite to the first end, of the common substrate. The common substrate may include circuit traces for interconnecting the superconducting components with the non-superconducting components. A heat-shield may thermally separate the first end from the second end of the common substrate such that the superconducting components are configured to operate in a temperature range between 2 Kelvin to 77 Kelvin and the non-superconducting components are configured to operate in a temperature range between 200 Kelvin to 400 Kelvin. Each of the superconducting components may be configured to provide primarily a processor functionality and each of the non-superconducting components may be configured to provide primarily a storage functionality.
