A quantum engineer’s portfolio spanning ion traps, FPGA laser locks, optical reconstruction, and an affordable microscope.

Landing page captured for the 2026-09-19 issue.
For
Physics and hardware builders
Worth noticing
The portfolio includes a 100 kHz laser lock with a 10 µs measurement window.

Field notes

The portfolio documents work across optics, superconducting circuits, trapped nanoparticles, FPGA systems, thermal engineering, and statistical physics. Its project entries name concrete methods and constraints, including a 550–700 nm spectrometer reconstructed with a convolutional autoencoder and a gravimeter built around a Paul trap. Eureka is shown as an ongoing build using Fusion 360, 3D printing, and plankton imaging, rather than as a completed product.
