pulses, which allow for the correction of various types of errors, which naturally arise in the system, by destructive interference of these errors. We use our approach to produce complete and partial population transfer between the qubit states, as well as the three basic single-qubit quantum gates. Our simulations show a substantial reduction of the typical errors and a gate speed-up by an order of magnitude.
Fast high-fidelity composite gates in superconducting qubits: Beating the Fourier leakage limit
We present a method for quantum control in superconducting qubits, which overcomes the Fourier limit for the gate duration imposed by leakage to upper states. The method uses composite
