Pelagic Systems

Pelagic Systems builds a control and calibration software stack for experimental quantum computers, spanning a context-aware data architecture, a reusable experiment framework, FPGA-based real-time control, and QCVV tools for characterising processor performance. The headline trick: it moves estimation and decision-making onto the controller's FPGA, so calibration happens inside the experimental loop rather than round-tripping through a host CPU.

Quantum hardware drifts constantly — qubit frequencies, lifetimes and readout parameters shift over time — so devices need frequent recalibration, and today's host-mediated feedback is a bottleneck. The company reports a T1 calibration that took around 250 ms via host feedback runs in about 10 ms on-FPGA, enabling continuous tracking and faster bring-up.

The company spun out of the Novo Nordisk Foundation Quantum Computing Programme at the Niels Bohr Institute in October 2026, where the founding team did hands-on research on superconducting qubits. Innovation Fund Denmark backed the underlying research through its Grand Solutions and InnoExplorer programmes.

The five-person founding team came out of hands-on superconducting-qubit research at NQCP, and the product builds directly on their own published work on millisecond-scale calibration and benchmarking. In other words, they're productising the problem they lived with daily.
