Abstract
The technology is generally directed towards a pulse generation component that outputs a control pulse with a timing delay. A qubit state decision component uses an analog kernel to perform a linear filtering operation on (e.g., multiplies and integrates) a qubit signal to obtain a result corresponding to a qubit state, and compares the result to a threshold value to determine a measurement outcome result corresponding to the qubit state. A conditional gate component conditionally gates the control pulse based on the measurement outcome result.
