Pulse optimisation has been implemented in system such as NMR to improve nuclear spin-readout fidelity. In this talk, we show that optimised microwave pulse calculated using GRAPE algorithm can improve our silicon spin qubit gate fidelities through simulation. Preliminary results of such optimised pulses that applied to our physical qubit will also be presented.
