Logiqal

I spent summer 2026 at Logiqal as a Quantum Hardware Intern. My work was on the software around the experiments: connecting instruments, calibrating optical waveforms, getting data off FPGAs, and keeping track of what was happening in the lab.

One of my main projects was a distributed NATS pub-sub network supporting more than 40 different instruments. I developed production device drivers, calibration services, and remote device management for the neutral-atom experiments.

The work covered both the individual devices and how they communicated across the network, so the drivers and services could be used together in an experiment.

I also developed a calibration pipeline for fiber-coupled acousto-optic modulators (AOMs). The goal was to get the optical output to match the requested waveform. I used complex-covariance demodulation and closed-loop pre-distortion, achieving less than 1% shape error in under 0.2 ms.

The basic idea is to measure the output, compare it with the target, and adjust the drive waveform to compensate for the difference.

On the acquisition side, I redesigned a Solarflare ef_vi kernel-bypass receive path for FPGA waveform data. I separated control traffic and jumbo-frame traffic into optimized RX queues, which increased throughput by 18×.

I designed a PostgreSQL/TimescaleDB backend for continuous laboratory monitoring. This included the hypertable schemas and compression and retention policies, so Grafana could query the data quickly over long time horizons.
