Quantum technologies ready for the real world
Developing quantum systems for real-world applications and fabricating quantum technology bricks through deep expertise in hardware design, miniaturization, and system-level engineering.
Quantum technologies harness quantum mechanical effects to keep time (quantum timing), measure (quantum sensing), transmit (quantum communication), or process information (quantum computing) with enhanced sensitivity, speed, and/or robustness. Quantum technologies promise extraordinary performance, but translating that promise into reliable, compact, and manufacturable systems is a challenge. Our unique strength is to combine in-house quantum hardware fabrication, advanced miniaturization, and system-level engineering to turn laboratory concepts into deployable quantum technologies.
With end-to-end capabilities from in-house fabrication of quantum technology bricks to system engineering and testing, CSEM helps industry turn lab-demonstrated quantum technologies into real-world quantum systems.
We offer proven platforms and expertise in quantum system integration, including complete quantum systems such as atomic clocks and quantum sensors, as well as technology bricks such as MEMS vapor cells, photonic integrated circuits, and quantum light sources. These are supported by the electronics, photonics, and miniaturized physics packages required to integrate them into real-world systems.
Research & development on Quantum Technologies
Our R&D activities focus on developing quantum timing and sensing systems, quantum hardware platforms, as well as enabling technologies that support integrated real-world quantum systems.
Quantum timing: atomic clocks
We develop atomic clocks based on rubidium hot vapor cells, transferring the stability of their atomic transitions onto a clock signal that serves as a stable frequency reference. Our portfolio includes:
- Miniature microwave atomic clocks optimized for low size, weight, and power consumption. They are enabled by our patented MEMS rubidium vapor cells, our physics package platform for miniature atomic devices, and our application-specific integrated circuits (ASICs).
- Compact optical atomic clock offering uninterrupted performance in a rack-compatible format. The all-optical operating principle enables new applications requiring high robustness and resilience.
Our roadmap focuses on pushing performance while preserving compactness and manufacturability, enabling deployment across space systems, terrestrial infrastructures, and scientific instrumentation.
Quantum sensors
We develop quantum sensors based on MEMS atomic vapor cells and diamond nitrogen-vacancy (NV) centers, enabling instruments such as magnetometers, gyroscopes, and radiometers with applications in space, healthcare, automotive, and energy.
- Our work builds on a mature sensor physics package platform that supports both hot vapor and NV centers. This platform has been used to demonstrate sensor prototypes such as magnetometers, RF sensors, and gyroscopes.
- We also evaluate emerging approaches such as Rydberg electrometry and diamond NV center-based sensors for future applications.
Our focus is on developing sensing technologies that combine quantum‑level performance with robustness, compactness, and the potential for industrial-scale deployment.
Quantum hardware
We design and fabricate quantum hardware that enables high‑performance quantum systems. Our capabilities span microfabrication, advanced materials, photonics, and precision engineering—performed in‑house to ensure full control over quality, compactness, and manufacturability.
Our activities include:
- Fabrication of MEMS vapor cells using advanced techniques, including patented wafer-level RbN3-based rubidium filling; high-vacuum-compatible materials and processes; Al2O3 protective coatings; and functionalization of glass windows such as integrated resistive heaters.
- Building components for quantum photonic integrated circuits (Q-PICs) on thin-film lithium niobate (TFLN), thin-film lithium tantalate (TFLT), and silicon carbide on insulator (SiCOI) platforms. We offer an open-access Multi-Project Wafer (MPW) service for prototyping.
- Creation of custom quantum light sources, including single-photon and entangled-photon sources.
These platforms provide technology bricks ready for integration into advanced quantum timing, quantum sensing, quantum communication, and quantum computing systems.
Quantum-enabling technologies
Quantum enabling technologies bridge the gap between core quantum components and fully functional quantum systems. We develop tailored electronics, photonics, and precision packaging solutions to drive, control, read out, and integrate quantum hardware with the low noise, high stability, and system-level performance required for real-world use.
Our activities include:
- Development of low-phase noise electronics tailored to high-performance quantum systems, and application-specific integrated circuits (ASICs) for ultra-low-power operation.
- Development of photonic components, including micro-optics light redistribution sheets and cryo-compatible microlens arrays for efficient interfacing of single-photon detectors.
- Design of compact physics packages for quantum components and of advanced packaging solutions for scalable quantum technologies and devices.
- Integration of complete quantum systems, ranging from chip-scale devices to rack-based instruments.
These enabling technologies support the transition from lab‑scale prototypes to fully manufacturable quantum systems.
