We present a method that allows quantum hardware to execute arbitrary operations at the pulse level by interpolating between a small number of known reference pulses. We demonstrate the procedure on the continuous space of all two-qubit operations.

We extend our previous work on qubit-to-ququart compression to specifically optimize three-qubit gates such as the Toffoli gate. We also find significant advantages in using Z-type multi-bit operations instead of X-type operations.
