• A time line of the steps forward in the development of quantum computing.
• In the scientific paper Simulating Physics with Computers Feynman mentions for the first time the potential of building a quantum computer.
• The scientific paper Cryo-CMOS Circuits and Systems for Quantum Computing Applications proposes a scalable solution for system integration at cryogenic temperatures.

• The guide Principles of dilution refrigeration gives some background on the refrigerators used for quantum computing. Dilution refrigerators have been used for cooling anything from millimetre-sized semiconductors to 3-ton gravitational wave detectors, down to milliKelvin (mK) temperatures.
