Kelvin Loh

Kelvin co-founded Orange Quantum Systems in 2020 as a QuTech spin-off. An applied mathematician by training with a focus on high-performance computing, he led the company's software development from 2020 to 2022 as maintainer of the open-source Quantify framework and the Superconducting Qubit Tools. From 2022 to 2024, as interim Commercial Director, he drove the first sales across the MAX and FLEX product lines. Since 2024 he is the Lead Product Manager for the MAX system, having deployed the OrangeQS MAX system to industrial customers and leading the partnership program to develop the next generation of high-throughput test systems.

Before OrangeQS, Kelvin worked at TNO, where his work bridged machine learning and physics-based modeling. He developed the first data assimilation approach coupling an ensemble Kalman filter with a physics-based LSTM network, applied to real gas fields; and performed charge stability diagram simulations using customized coupled TCAD and Schrödinger-Poisson FEM solvers for real double quantum dot devices using actual SEM geometry, demonstrating a feasible closed-loop feedback development cycle for spin qubit devices.
