Center for Nanotechnology and Nanomaterials

Welcome to the Quantum Sensing group
Group leader: Dr. Friedemann Reinhard (Emmy Noether fellow)

Research in our group focuses on quantum sensors and their applications, with a particular focus on applications in the life sciences.

[Reinhard 1] As one of our foremost goals we aim to demonstrate nuclear magnetic resonance (NMR) spectroscopy on single biomolecules. This ambitious vision has recently become a realistic prospect by the use of color centers in diamond as nanoscale NMR detectors. These atomic-size crystal defects can serve as a quantum sensor for magnetic fields. Meanwhile, we routinely employ them to detect the nuclear magnetization of a sample volume as small as few nanometers, comparable in size to a single biomolecule.

Recent News

2017 / 10 / 18 - Quantum sensing of GHz frequency signals
[Reinhard 2] Quantum sensors can detect signals at much higher frequencies than previously thought. This is a finding we report in Nature Communications this week. Our scheme could lead to a new generation of quantum devices, such as detectors for single microwave photons.

2017 / 09 / 27 - Research prize for Wi-Fi holography
[Reinhard 3] Our holographic imaging technique for wireless radiation has been awarded the Research and Solutions award of the trade fair RFID and Wireless IoT Tomorrow. Congratulations to everyone involved and thanks to the RFID industry for supporting our work in this way!

2017 / 07 / 25 - Review on Quantum Sensing in Rev. Mod. Phys.
[Reinhard 4] We have teamed up with the labs of Christian Degen (ETH) and Paola Cappellaro (MIT) to write a review article on our field of research, aiming to provide a starting point for beginners and a reference for experts.

2017 / 05 / 05 - Wi-Fi holography article appears in Phys. Rev. Lett.
[Reinhard 5] We have recorded holograms of building interiors, illuminated by the stray radiation of Wi-Fi routers. Our work appears in Phys. Rev. Lett. this week and is covered by Science, APS Physics and international media. You can read it here, it is open access, or watch our supplementary video.
