Quantum Computing in NMR in zero field vs high field

Quantum computing is one of the leading topics in modern physics, and among different attempts to address this topic, one of the popular choice are the NMR experiments. Recently, NMR experiments can be performed not only in high-field but also in ultralow or even in zero-field. Such a transition not only gives a lot of profits, like long coherence times, but also raises a series of problems that need to be addressed. During this seminar, I will describe the main differences between these two field regimes and the challenges to overcome to ensure system controllability.
