The quantum detection department addresses the development of detectors and measurement systems for detection at the quantum limit. This includes ultra-sensitive bolometers, thermal sensors for the infrared and terahertz ranges, and magnetometers that make use of quantum effects to achieve extreme sensitivities. The development and production of detectors is based on highly-developed micro and nanotechnology. These detectors are used in novel measurement systems that allow spatial and temporal monitoring.
The key focus of research in this department includes:
- Quantum-limited magnetometers
- Quantum radiometry
- THz imaging systems and spectrometers
- Quantum-limited photonic detectors
- Uncooled thermal IR and THz sensor systems
- Micro/nanotechnology for photonic instrumentation
The research performed in the quantum detection department has produced versatile applications. The department’s expertise ranges from the production of highly-integrated circuits and sensors from different materials to the development and assembly of complex measurement systems.
Primary applications include:
- Biomagnetism: Measurement of human, even fetal, heart signals without costly shielding
- Geophysical exploration: Surveying for new raw materials
- Archaeology: Tracing our ancestral tracks
- Voltage norm: Quantum-precise voltage generation as fundamental unit
- Superconducting radiation detectors and IP sensor systems: radio astronomy and security technology
