Electronics for photoelectric (PE) readout are on-diamond electronic structures that collect charge generated during optical excitation of NV centres. They are essential because they enable fast, compact, and scalable electrical readout, replacing bulky optical systems and allowing quantum devices to be miniaturized and manufactured at scale. We have developed the key know-how for on-diamond electronics at nm scale and demonstrated PE readout, that can be transitioned to manufacturing scale.

We have developed key capabilities to enhance the light delivery for the initialization of the qubits. This allows to improve optical efficiency and increase the signal-to-noise ratio for PE readout.
