Application laboratory quantum sensing

Several quantum magnetometers are available to enable partners from science and industry to evaluate the innovation potential of quantum sensors for their specific requirements. We are looking forward to getting to know potential users, their questions and project ideas!

We would be happy to keep you informed about our application laboratory quantum sensing. Please contact us: quantum@iaf.fraunhofer.de

Nitrogen-vacancy centers in diamond

NV centers are individual atomic systems that act as highly sensitive sensors. Their unique advantage is their potential to be operated at room temperature and on background fields. They allow for extremely high spatial resolution and are being utilized in different imaging measurement methods.

• Widefield magnetometry provides a unique compromise between spatial resolution and measurement time. It allows for the quantitative imaging of magnetic fields and fluctuations.
  
• Scanning probe quantum magnetometers allow to measure magnetic field distributions at the nanoscale.
  
• Laser threshold magnetometers are currently being developed and will enable measurements of the smallest magnetic fields, such as those generated by brain waves at room temperature and on background fields.
  
• Radio-frequency (RF) sensors with optical readout are being developed that analyze the time-frequency behavior of complex, agile RF signals.

Qnami ProteusQ

The Qnami ProteusQ is an adapted atomic force microscope and a plug & play device, complete with electronics and software. It is not necessary for customers to have special expertise in quantum sensing, since it offers automated operations and the tip and sample exchange takes just a few minutes. The system measures small DC magnetic fields with atomic spatial resolution and is well suited to investigate materials science questions.

attocube CSFM

This system is an atomic force microscope combined with a confocal microscope, which offers extreme stability. At Fraunhofer IAF, this system is modified to a quantum magnetometer. For this purpose, the laser, the single photon detector and the microwave source will be integrated and programmed. It will also be possible to incorporate different diamond tips and measure both DC and AC currents. This makes it a versatile magnetometer that can be adapted to various quantum sensor applications.

QZabre QSM

This system will be available soon. It is a plug & play AFM with two additional features: AC magnetometry and the magneto-optical Kerr effect. The first allows measurements that require high sensitivity, the second measures the magnetization of samples. Since the microwave antenna is integrated into the diamond probe, this magnetometer is perfectly suited for sample comparison studies.
