Abstract
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 provide an experimental proof-of-concept of these operations by using 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. This modulation scheme is straightforward to implement in practice and can be deployed to any other qubit-based experimental platform.Description
