The QICK box, a new modular and scalable hardware platform for quantum control
Oral-In-person
Abstract
We describe hardware, firmware and software advances for the open-source QICK (Quantum
instrumentation Control Kit) that are now integrated in a custom box. The QICK box features 16
outputs, 8 inputs and 8 20-bit DC biases. Modular output and input daughtercards give the choice
of signal chains optimized for fast DC-coupled signals or RF signals up to 10 GHz. Power levels,
step attenuation and bandpass filtering are controlled by software. Our Xcom protocol connects up
to 16 QICK boxes, providing synchronization to a master clock with < 100 fs jitter allowing pulse
and phase stability across all boxes, and all-to-all communication with latency < 200 ns allowing
large systems and lower level QEC protocols at the firmware level. Xcom can also be connected to
a central communication hub or used as an interface to other hardware.
