About

Nir Bar-Gill’s research aims to create a new platform for both fundamental studies in quantum science and interdisciplinary applications.

Specifically, his current focus is on the nitrogen-vacancy (NV) centre – a unique, naturally occurring colour centre in diamond, which can serve as a building block for quantum information processing.

The NV centre has remarkable quantum properties, which are readily accessible even in 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 to serve as building blocks for quantum processors. This could have profound implications in all aspects of information technology, including computing, communications and cryptography. Bar-Gill’s recent work has contributed to this endeavour, extending the NV quantum coherence time to one second, a significant improvement over previous results.

In addition, the spin properties of NVs allow them to act as very sensitive magnetic sensors. So NV-carrying diamonds and nano-diamonds could be used for highly sensitive magnetic resonance imaging (MRI), as exists 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.
