Monarch Quantum selected for NASA JPL Quantum Gravity Gradiometer Pathfinder photonics

Monarch Quantum was selected to supply integrated photonics Quantum Light Engines for NASA Jet Propulsion Laboratory's Quantum Gravity Gradiometer Pathfinder mission. The company will provide laser-optical subsystems to Infleqtion for integration into the sensor's quantum core for future flight demonstration. The mission is intended to demonstrate the first planned space deployment of a neutral-atom quantum gravity gradiometer for high-precision Earth observation and navigation applications. Monarch Quantum's Quantum Light Engines integrate multiple chip-scale lasers, hundreds of precision optical components, low-noise control electronics, advanced thermal and mechanical stabilization and factory-aligned sealed photonics packaging into a single ruggedized module. The systems are designed to meet requirements for size, weight and power optimization, alignment stability under vibration and launch loads, thermal resilience in orbital environments, reduced system integration complexity and long-term operational reliability. NASA Jet Propulsion Laboratory and Infleqtion plan to complete the instrument hardware development over the next three years followed by flight demonstration. Dr. Timothy Day, Chairman and CEO of Monarch Quantum, said the company is honored to support the mission and to serve teammates in advancing space-based quantum sensing. The executive noted the collaboration with NASA JPL in Southern California, NASA's Goddard Space Flight Center, Infleqtion and industry partners.
