Composite pulses for nitrogen-vacancy colour centres — Josselin Bernardoff, •Jan Thieme, Ricky-Joe Plate, Manika Bhardwaj, Markus Debatin, and Kilian Singer — Universität Kassel, Kassel, Deutschland

We present numerical and preliminary experimental results of the application of tailored composite pulses [1] to shape the excitation profile addressing only selected quantum states in the system. By using analytical methods applied to the Rosen-Zener excitation model [2], we derive excitation profiles for a broadband excitation profile with respect to detuning and pulse duration. Towards this goal we are using an arbitrary waveform generator to supply these pulses to single nitrogen-vacancy colour centres. As an outlook we will show how the derived pulse sequences can be extended to qubit manipulation in trapped ions.
