What background is expected of a quantum computing researcher?
Quantum computing researchers are expected to have a good understanding of mathematics, physics, and computer science concepts. In addition, having a strong theoretical and research background is helpful.
Although a degree in one of these fields will be useful, it is not an absolute requirement for some quantum computing positions. As the field of quantum computing is growing, companies are starting to spread its applications to different areas, such as finance and engineering. So, it is possible that in the future, there will be positions in quantum computing research that do not strictly require someone to have a strong mathematics, physics, and computer science background.
