Integrated Quantum Sensors

Quantum technologies enable a new generation of optical and electronic devices based on quantum states and their precise manipulation, thus opening up new prospects in numerous fields of application.

In the Joint Lab Integrated Quantum Sensors (IQS) we aim to develop the next generation of chip-scale quantum sensors for real world applications. These sensors use high-precision spectroscopy techniques applied to atomic or molecular ensembles either at room temperature or near absolute zero using laser cooling and advanced cooling mechanisms. Here, the intrinsic properties of quantum mechanical states and their precise manipulation with laser light are exploited in order to realize instruments for highly accurate measurements of physical quantities, such as frequency, time, inertial forces as well as electrical and magnetic fields.

Our main focus

Together with the activities located at HU Berlin, we target these research topics

Optical Clocks

Optical clocks based on thermal and cold atomic gases for use in navigation and data syncronisation processes

Atomic Quantum Memories

Atomic quantum memories for measurable security in data transfer

Field Sensors

Atom-based concepts for the measurement of physical fields

Laser Systems

Compact and robust laser systems for manipulation of Bose-Einstein condensates

Reserch and development is carried out in close cooperation and is strategically synchronized with activities of the Joint Lab Quantum Photonic Components (QPC) at FBH. Together, we cover the full technology chain from components to systems. Activities include modeling of photonic components, hybrid micro-integration of electro-opto-mechanical devices, system design, verification, and finally the operation of quantum sensors. In particular, we make use of these technologies:

Additive Manufacturing

Generative manufacturing technologies (ceramics, thermoplastics) combined with microtechnological assembly and coating technologies for compact, scalable assemblies.

UHV Optical Systems

Fiber-coupled, miniaturized free-space optical systems for atomic manipulation in UHV envitoments

Vacuum Technology

Development and qualification of joining processes and electro-optical components for use in UHV systems and space applications.

Quantum sensors are important building blocks for future applications in space and fundamental science missions, e.g., for the next generation of global navigation satellite systems, Earth observation, and fundamental tests of gravity. Together with the Optical Metrology Group at the Humboldt-Universität zu Berlin (HU Berlin), several generations of miniaturized laser payloads and autonomous, absolute optical frequency references for operation on sounding rockets have been developed. Our current activities specifically address research and development for related technologies on small satellites. With a reduction in cost, increase in performance and the possibility to realize short-mission development times this satellite class is predestined for demonstrating enabling technologies in space.
