Quantum Characterization, Verification, and Validation Engineer

PsiQuantum is seeking a researcher to develop methods for quantum characterization, verification, and validation (QCVV) of large-scale quantum systems. The successful candidate will work on methods for reliably characterizing quantum channels and system-level behavior in regimes where direct reconstruction is impossible. This includes developing scalable protocols, statistical analysis techniques, and simulation methods that connect experimental data to actionable conclusions about quantum performance.

Large-scale simulation is an important part of this role, particularly in the context of characterizing quantum channels, validating QCVV protocols, understanding error mechanisms, and predicting how characterization methods perform on large systems. Relevant experience may include tensor network methods, GPU-accelerated simulation, Monte Carlo methods, stabilizer simulation, and other approaches for modeling large quantum circuits and noisy quantum processes.

PsiQuantum’s architecture is based on photonic quantum computing. Prior experience with photonic quantum computing is valuable but not required. Candidates should be eager to learn the relevant photonic concepts and apply their QCVV, modeling, and simulation expertise to a photonic fault-tolerant quantum computing platform.

This is a hands-on technical role in a fast-moving environment. The ideal candidate is comfortable owning research projects end to end, working across disciplines, communicating uncertainty clearly, and translating technical results into decisions that improve system characterization and performance.
