Pursuing a research career in quantum computation in the UK presents challenges due to limited active research in the field. Quantum computing is described as a broad theme encompassing various disciplines, including quantum optics and computer science, rather than a standalone area. While there are a few groups in the UK, such as an algorithms group at Cambridge and labs at Oxford and Sussex focusing on Quantum Ion Trap computers, most work is considered peripheral or a spin-off from other quantum technologies. The UK has shifted its focus away from quantum computing to areas like quantum cryptography, leading to funding difficulties for quantum computing projects. For more substantial opportunities, the US is recommended as the leading country for quantum computing research, with Canada, Australia, and Japan also being viable options.
