(Futurism) Collecting parts for quantum computers is so difficult and expensive and could slow the development of the technology as a whole. Specialized parts like refrigerants that keep quantum computers near absolute zero and superconducting cabling are reported to be practically impossible to obtain right now.
Demand for these specialized parts is outstripping the dwindling supply. Many quantum computing components are made by only one or two companies in the entire world, i.e., cables that conduct very little heat are made by just one manufacturer in Japan.
The path to increasing the supply of quantum computing components is uncertain. Perhaps current manufacturers will expand to catch up with the growing demand for the components needed for today’s quantum computers. Or smaller companies could enter the market and start manufacturing some of the rare components as demand increases.
