Raman Pandey

Graduate Research Assistant at the Center for High Technology Materials (CHTM), University of New Mexico, in Prof. Marek Osinski's group. I work on the NSF NQVL QCAP project — electrically driven semiconductor quantum-dot single-photon sources, aimed at room-temperature operation with in-plane SiN waveguide coupling. Co-advised on continuous-variable photonic quantum error correction by Prof. Olivier Pfister at the University of Virginia.

BS in Computer Engineering and Astrophysics (UNM, 2025) → MS in Electrical and Computer Engineering, quantum information concentration (2026) → continuing into a PhD in ECE (QIS) in Prof. Osinski's group at CHTM.

What I work on

  • Quantum-dot single-photon sources — electrically driven semiconductor QD emitters targeting room-temperature operation with in-plane SiN waveguide coupling; device modelling public in qd-photon-sim.
  • Programmable photonics (MZI meshes) — simulating and programming Clements/Reck interferometer meshes, unitary decomposition, and Fock-state amplitudes; public as MZIMesh.
  • Continuous-variable photonic QEC — code theory and encoding circuits, and resource-overhead calculation for CV codes.
  • Single-photon detector readout — SPAD and SNSPD instrumentation, including FPGA time-to-digital conversion (FPGAReadout-Vivado-code).
  • Clocks and timing — precision clock and synchronization systems for photonic experiments.
  • Systems-level engineering — the connective tissue for all of the above: HDL, embedded firmware, lab instrumentation, and full-stack software. The personal repos below are the same skill set off the clock.

Everything else here is personal engineering — local-first AI, embedded and FPGA builds, and full-stack side projects — kept public and described plainly rather than curated away.
