Quantum information processing (QIP) can be performed using any multi-state quantum system that is sufficiently isolated from its surrounding thermal and dissipative environment while also being sufficiently controllable and addressable. These systems function as quantum bits (qubits) and quantum-limited sensors that are used for information-processing tasks such as computing and sensing. Leveraging the incredible technology and related infrastructure developed for integrated solid-state systems, such as CMOS, is expected to yield efficient routes to realize densely integrated QIP systems with many more qubits, which is much more computationally powerful than demonstrated systems (with qubit numbers of order 100).
