Many national governments around the world are investing significantly in the potential for economic growth and increased opportunity based on new systems, products and services using the quantum properties of materials. These properties are best described by the equations of quantum physics and the resulting devices and systems are collectively known as quantum technologies.
These include the increased sensitivity of quantum sensors and imaging devices, the increased precision of quantum clocks, the increased security of quantum communication, and the increased power of quantum computers.
As those technologies near market there needs to be a parallel increased focus on building a solid industrial base, including the creation of new standards and possible new regulations to form part of the developing industrial and commercial landscape for quantum technologies.
Standards will play an important part in enabling integration of quantum devices into wider complex systems. The existence of standards supports the test and measurements needed for validation of quantum enabled measurement systems and procedures. By achieving global agreement on how measurements should be made, expressed, and used, we can be sure that measurements will be stable over time, comparable with others and accurate, allowing known confidence in measurement results.
In this special issue, we invite authors to submit contributions which describe (for a wide audience) recent work towards the development of new standards for quantum technologies. In particular, authors from industry and applied research organizations, but also from academia, are invited to submit contributions that fit this theme. The editors are interested to see any articles which are supportive of a measured approach to standardisation; enabling innovation while not restricting creativity.

Random numbers constitute an important part of science, finance, engineering, and contemporary cryptographic systems. Large number of everyday applications, such as mobile communications, non-cash payments, emailing, internet-banking, cryptocurrency, blockchain networks, use certain sources of randomness. Overwhelmingly, these sources represent computer algorithms for generating pseudorandom numbers, which are potentially vulnerable for various attacks. Emerging quantum computers could make pseudo-randomness-based cryptographic systems defenseless; therefore, much attention is paid today to quantum key distribution or “quantum cryptography” systems, where quantum random number generators (QRNGs) take a special place.
