Spin Quantum Computing with Molecular-Encaged Atomic Hydrogen

Atomic hydrogen is useful in quantum computing applications, owing to its simple atomic structure and the lack of complex magnetic interactions - a characteristic that is crucial for preserving the fragile electron spin coherence. Trapped in proper molecular nanocages, the otherwise highly reactive hydrogen atom becomes stable even at room temperature. This article discusses the aims of the active INN research project, "Spin-Based Quantum Computing", along with the recent developments in the design and characterisation of encaged atomic hydrogen as spin qubit.
