Stabilization of a silicon double quantum dot based on a multi-dimensional gradient descent technique
With a view to long-term qubit device operation, we report on a method to stabilize a silicon double quantum dot against slow drift in a two-dimensional gate-voltage space based on a current gradient-based feedback technique. We demonstrate that, unlike conventional single-axis feedback schemes, our...

| description | With a view to long-term qubit device operation, we report on a method to stabilize a silicon double quantum dot against slow drift in a two-dimensional gate-voltage space based on a current gradient-based feedback technique. We demonstrate that, unlike conventional single-axis feedback schemes, our method can maintain the double-dot potential configuration. We measure a feedback bandwidth of up to 300 mHz, consistent with the sampling rate and the digital filter cutoff frequency used in the experiment. |
