“Sense and Sensibility: Practical Quantum Sensing”
presented by Dr. Danielle Braje, MIT Lincoln Laboratory

From the movement of a glacier 20,000 years ago to testing fundamental laws of physics, quantum systems have been used to make the most accurate measurements known to man. This impressive precision and accuracy is often paired with an equally imposing size where “compact systems” span the entirety of an optics table. We present an alternative approach to the massive apparatus that accompanies the traditional atom interferometers used in quantum sensing. By using quantum color centers in a solid-state system, nitrogen vacancies in diamond, we gain many of the advantages of traditional atom interferometry while using a millimeter-scale diamond package. In particular, we demonstrate a room-temperature nitrogen vacancy magnetometer with sensitivity/stability rivaling that of its classical counterparts.

“There is widespread belief that fundamental ideas from QIS will lead to useful new information technology, and provide computing, communication, and control systems beyond the limits of traditional paradigms. These carry with them profound social implications. This is why iQuISE will incorporate education in ethics and social context.”
