Quantum computing is an emerging technology that leverages the principles of quantum mechanics to solve complex problems beyond the capabilities of classical computers. Quantum computers use qubits, which are individual atoms, electrons, photons, or man-made circuits operating at extremely low temperatures, as their processing units. While basic quantum computing has been demonstrated, the challenge lies in scaling up these systems while maintaining their quantum properties. NPL is well-equipped to support this transition, drawing on years of experience with quantum standards. We contribute to technical evaluation, component characterisation, and the development of documentary standards to define terminology, specifications, and test methods for quantum computers, helping to advance this promising technology.
