We present a set of robust and high-fidelity pulses that realize paradigmatic operations such as the transfer of the ground state population into the excited state and arbitrary X/Y rotations on the Bloch sphere. These pulses are based on the phase modulation of the control field. We implement these operations on a transmon qubit, demonstrating resilience against deviations in the drive amplitude of more than ≈20% and/or detuning from the qubit transition frequency in the order of 10MHz. The concept and modulation scheme is straightforward to implement and it is compatible with other quantum-technology experimental platforms.
