Open source quantum defect controller: QICK-DAWGv1.0

The Quantum Instrumentation Control Kit - Defect Arbitrary Waveform Generator (QICK-DAWG) is an open sources quantum hardware project that extends QICK with the purpose of controlling quantum defects for quantum sensing and other quantum applications. This presentation discusses recent advancements in the firmware, hardware, and software of QICK-DAWG and the new measurements these have enabled. Our newest firmware includes edge counting mode for counting TTL signals from single photon detectors enabling detection of light down to the single quantum defect level. We’ve also designed a tested a real time signal generator that produces dynamic decoupling sequences with 300ps resolution. On the software side, we’ve implemented new experiment designs that enable CPMGXY-8 pulse sequences and frequency ramps for Landau Zener transitions. As for hardware, our most recent release includes designs for the “DAWG-House” a rack mount enclosure for ZCU216, ZCU111, and the RFSoC4x2 FPGA evaluation boards and enclosure mounted PCBs for differential amplification to ADCs and low impedance amplifiers for 5V output triggers.
