Nir Bar-Gill’s research aims to create a new platform for both fundamental studies in quantum science and interdisciplinary applications. Specifically, Nir currently focuses on the nitrogen-vacancy (NV), a unique naturally occurring color center in diamond that can serve as a building block for quantum information processing.

The NV center has remarkable quantum properties, which are readily accessible even at ambient conditions. Therefore, diamond-based devices embedded with these NVs could lead to breakthrough applications in a wide range of fields. For example, NVs are currently leading candidates for serving as building blocks for quantum processors, which could have profound implications in all aspects of information technology, including computing, communications and cryptography. Nir’s recent work has contributed to this endeavor, extending the NV quantum coherence time to 1 second, constituting a significant improvement compared to previous results. In addition, the spin properties of the NVs give them the ability to act as very sensitive magnetic sensors. Therefore, NV carrying diamonds and nano-diamonds can be used for highly sensitive Magnetic Resonance Imaging (MRI), as is used today in hospitals, but in a small, portable package. Such sensitive diamond-based MRI devices could be used in medical applications, as well as in fundamental research.
