About Us planqc builds neutral-atom quantum computers based on arrays of optically trapped atoms controlled with high-precision laser systems. Our platform combines technologies from optical lattice clocks, quantum gas microscopes and fast Rydberg gates into a scalable computing architecture. Founded in 2022 as a spin-off from MPQ and LMU Munich, we translate more than a decade of AMO research into deployable quantum systems. Our work spans vacuum and laser hardware, control electronics, firmware, system software and algorithm integration. We focus on turning complex experimental setups into stable, reproducible systems that operate in real computing environments. Behind this technology is a team that pushes technical boundaries, values open exchange and shared ownership. Physicists, engineers, software developers and business specialists work closely together, often across disciplinary limits. We believe progress comes from combining deep expertise with practical engineering and from giving people the responsibility and trust to shape their domain. As we grow across our locations in Garching, Ulm, and Innsbruck, we continue to build a company where people take ownership, learn from each other, and directly shape the systems we bring into operation.
