Enhanced spin coherence at the sweet spot of a self-assembled quantum dot molecule

A pair of coupled dots with one electron in each dot can provide improvements in spin coherence, particularly at an electrical bias called the sweet spot, but few measurements have been performed on self-assembled dots in this regime. Here, we directly measure the \(T_2^*\) coherence time of the sin...
