Our mission is to build scalable, field-deployable quantum networks through solid-state quantum memory and networking technologies designed to operate beyond the laboratory and integrate directly with real-world infrastructure. At Qunett, physicists and engineers work hands-on with diamond-based quantum devices, photonics, cryogenic systems, and control electronics to translate fundamental quantum capabilities into practical networked hardware. This is a ground-floor opportunity to help shape how quantum systems communicate, scale, and drive the next generation of secure communication, distributed sensing, and quantum computing. As an early-stage company actively building out its quantum memory and photonics teams, Qunett seeks physicists and engineers who bring technical range, adaptability, and readiness to contribute across disciplines as the technology and team evolve.About Qunett\r\nQunett is developing the foundational hardware layer for quantum networking.
