Coherent Manipulation of a Molecular Ln-Based Nuclear Qudit Coupled to an Electron Qubit

摘要

We demonstrate that the [Yb(trensal)] molecule is a prototypical coupled electronic qubit–nuclear qudit system. The combination of noise-resilient nuclear degrees of freedom and large reduction of nutation time induced by electron–nuclear mixing enables coherent manipulation of this qudit by radio frequency pulses. Moreover, the multilevel structure of the qudit is exploited to encode and operate a qubit with embedded basic quantum error correction.
