説明:

Geometric effects can play a pivotal role in streamlining quantum manipulation. We demonstrate a geometric diabatic control, that is, perfect tunneling between spin states in a diamond by a quadratic sweep of a driving field. The field sweep speed for the perfect tunneling is determined by the geometric amplitude factor and can be tuned arbitrarily. Our results are obtained by testing a quadratic version of Berry’s twisted Landau-Zener model. This geometric tuning is robust over a wide parameter range. Our work provides a new basis for quantum control in various systems, including condensed matter physics, quantum computation, and nuclear magnetic resonance.
