quantum gravity gradiometer technical

"represents the first planned space deployment of a quantum gravity gradiometer — a neutral-"

A quantum gravity gradiometer is a high‑precision sensor that detects tiny differences in the strength of gravity across short distances using quantum‑based measurements. Think of it as a very sensitive ruler for gravitational changes: it can reveal hidden structures underground, track mass movements, or improve navigation where GPS fails. Investors care because the technology can enable new services in resource exploration, infrastructure monitoring, defense and advanced navigation, creating potential commercial and government demand.

neutral-atom quantum sensor technical

"space deployment of a quantum gravity gradiometer — a neutral-atom quantum sensor designed"

A neutral-atom quantum sensor uses clouds of electrically neutral atoms controlled with lasers and magnetic fields to exploit quantum behavior for measuring minute changes in forces, time, magnetic fields or motion. Think of it as a microscopic, ultra-precise compass or clock that reads tiny signals ordinary sensors miss; for investors, such devices promise higher performance in navigation, timing, imaging and industrial sensing that can create new markets or give competitive edges in existing ones.

integrated photonics technical

"quantum photonics company specializing in integrated photonics systems for quantum computing,"

Integrated photonics are tiny chips that route and process light signals the way conventional microchips handle electricity, combining lasers, waveguides and detectors onto a single compact device. For investors this matters because these chips can enable much faster, lower‑power and smaller systems for data centers, telecom, sensors and emerging technologies; that potential for cost reduction, performance gains and new product opportunities can drive revenue growth and competitive advantage.

quantum sensing technical

"systems for quantum computing, quantum sensing, and quantum communications, today announced"

Quantum sensing uses the unusual behavior of tiny particles to measure physical quantities—like magnetic fields, time, or motion—with far greater precision than conventional sensors. For investors, it matters because this leap in sensitivity can enable new products and markets (better medical imaging, navigation without GPS, or faster material testing), potentially creating high-growth opportunities for companies that commercialize reliable, scalable devices.

inertial navigation systems technical

"climate monitoring, and next-generation inertial navigation systems that operate without GPS."

Inertial navigation systems are self-contained motion sensors and software that track an object’s position and orientation by measuring its accelerations and rotations, without relying on external signals like GPS. Think of it as counting steps and turns in the dark to know where you are; for investors, these systems matter because they enable reliable navigation in airplanes, ships, drones, and autonomous vehicles, influencing product value, safety claims, and market demand.

Size, Weight, and Power (SWaP) technical

"The systems are designed to meet stringent requirements for:Size, Weight, and Power (SWaP) opt"

A size, weight, and power (SWaP) swap means replacing one piece of equipment or component with another that has different physical dimensions, mass, or energy needs. Investors care because these swaps can change a product’s cost, ease of installation, operating expenses and market appeal—like trading a large, power-hungry appliance for a smaller, energy-efficient model—affecting margins, customer demand and future upgrade costs.

vacuum systems technical

"consist of multiple tightly coupled subsystems, including atom sources, vacuum systems, laser"

Vacuum systems are equipment that remove air and other gases from a sealed space to create a low‑pressure environment used in manufacturing, laboratory work, and medical devices. They matter to investors because they are core capital goods for industries like semiconductors, pharmaceuticals and advanced manufacturing—think of them as industrial 'vacuum cleaners' that enable precision processes—so sales, service contracts and supply chain positions can signal durable revenue and technological competitiveness.

control electronics technical

"atom sources, vacuum systems, laser and optical assemblies, control electronics, and data proc"

Control electronics are the electronic circuits and components that act like a device’s brain and nervous system, sensing conditions, making decisions, and sending signals to motors, displays, or power supplies to make the product operate as intended. For investors, the quality and design of control electronics affect performance, reliability, manufacturing cost, product differentiation and supply-chain risk, so they influence margins, customer satisfaction and a company’s ability to scale.

SAN DIEGO, Feb. 25, 2026 /PRNewswire/ -- Monarch Quantum, Inc., a U.S.-based quantum photonics company specializing in integrated photonics systems for quantum computing, quantum sensing, and quantum communications, today announced its selection to deliver Quantum Light Engines^™ for NASA's Jet Propulsion Laboratory (JPL) Quantum Gravity Gradiometer Pathfinder (QGGPf) mission.

QGGPf represents the first planned space deployment of a quantum gravity gradiometer — a neutral-atom quantum sensor designed to measure minute variations in Earth's gravitational field from orbit. Space-based quantum gravity sensing enables ultra-precise Earth observation, subsurface mapping, climate monitoring, and next-generation inertial navigation systems that operate without GPS.

Monarch Quantum will supply its integrated photonics Quantum Light Engines^™ directly in support of Infleqtion (NYSE: INFQ), a publicly traded quantum technology company and global leader in neutral-atom quantum sensing and quantum computing. Infleqtion will integrate Monarch Quantum's laser-optical subsystems into the quantum core of the gravity sensor.

Enabling Space-Qualified Quantum Sensing

Quantum gravity sensors rely on highly stable laser and photonics control systems with sub-milliradian alignment stability to cool, trap, and manipulate neutral atoms. Neutral atom quantum sensors require ultra-stable laser frequency control and phase coherence that, historically, have not been suitable for deployment in space environments due to size, weight, power, and environmental sensitivity constraints of laboratory-grade photonics assemblies.

Monarch Quantum's Quantum Light Engines^™ solve this challenge by integrating:

• Multiple chip-scale lasers
• Hundreds of precision optical components
• Low-noise control electronics
• Advanced thermal and mechanical stabilization
• Factory-aligned, sealed photonics packaging into a single, ruggedized module engineered for space deployment.

The systems are designed to meet stringent requirements for:

• Size, Weight, and Power (SWaP) optimization
• Alignment stability under vibration and launch loads
• Thermal resilience in orbital environments
• Reduced system integration complexity
• Long-term operational reliability

By consolidating complex laser-optical architectures into compact, space-qualified photonics engines, Monarch Quantum reduces integration risk while accelerating mission readiness.

Systems Engineering and Risk Reduction

Space-based quantum gravity gradiometers consist of multiple tightly coupled subsystems, including atom sources, vacuum systems, laser and optical assemblies, control electronics, and data processing units. Many of the required photonic components are not commercially available at scale.

Monarch Quantum applies advanced systems engineering methodologies to translate mission-level flow-down requirements into subsystem and component specifications. This structured approach mitigates system integration risk, ensures performance margin, and supports accelerated deployment timelines for high-reliability quantum sensing missions.

Strengthening U.S. Leadership in Quantum and Space Technologies

"We are honored to support this historic mission and to serve our teammates in advancing space-based quantum sensing," said Dr. Timothy Day, Chairman and CEO of Monarch Quantum. "The QGGPf mission represents a major milestone in U.S. leadership in quantum gravity sensing and precision measurement from orbit. We are proud to collaborate with NASA JPL here in Southern California, NASA's Goddard Space Flight Center, Infleqtion, and our industry partners to help enable the first planned space deployment of a quantum gravity gradiometer."

NASA JPL and Infleqtion plan to complete the instrument hardware development over the next three years, followed by flight demonstration.
