QZabre: an unconventional quantum startup

QZabre

QZabre is an ETH Spinoff founded in 2018 commercializing the quantum sensing technology developed in Prof. Degen's Spin Physics Group. We use single defects in diamond, Nitrogen Vacancy centers, as atomic scale sensors. By scanning the sensor over the sample, we create images of magnetic and electric fields, microwave magnitudes and temperatures with <25 nm resolution. Our products are used in applications ranging from academic research to semiconductor R&D, with a growing customer base. We invest a significant part of our revenues into R&D to not only improve the performance of our products, but also to make NV technology more useful both to current and also new applications. Most of QZabre's currently 17 employees are physicists and we all enjoy the challenges of creating high tech products almost from scratch, incorporating the most recent of both scientific and technology advances.

About the speakers:

Dr. Gabriel Puebla Hellmann is CEO of QZabre, an ETH Spinoff that creates NV Magnetometry products. An enthusiast for moving quantum technologies from the lab to real world applications, he started his career with a PhD in Prof. Andreas Wallraff’s Quantum Device Lab at ETH Zürich, finishing in 2012. He then moved to IBM Zürich, where he worked to create a mass-fabrication compatible platform for molecular electronics. Mid 2018, immediately convinced of the potential that NV technology offers, he joined QZabre as a late cofounder. Dr. Puebla Hellmann has authored scientific papers published in Nature as well as several patents and won the Zeiss Quantum Challenge in 2020.

Björn Jósteinsson is a Quantum Software Engineer at QZabre. Originally from Iceland, he relocated to Switzerland to pursue a master’s degree in Quantum Engineering at ETH Zurich. During his time at ETH, he joined forces with QZabre through a semester thesis with the Spin Physics Group and later an internship at QZabre, where he implemented a method to accelerate scanning NV measurements. With a background in both quantum and magnetism, Björn finds great fulfillment in working with NV sensing, a field that combines these two areas. At QZabre, he is responsible for software development, system assembly, conducting measurements and training users.
