Leveraging novel materials for quantum sensing

In this talk, we will describe an experimental framework that leverages quantum phenomena to inform and explore the unique role that material physics can play in developing more sensitive and efficient quantum devices. The overarching challenge of utilizing novel materials in quantum devices is the integration of the material into the device in such a way that unlocks new functionality. We address this challenge by leveraging the characteristics of two-dimensional (2D) van der Waals (VdW) materials such as gate-tunability, pristine interfaces, and emergent electronic properties of their heterostructures to welcome a new era of hybrid superconducting devices. To this end, we present our latest measurements of the internal energy of a single photon and describe a method to directly detect the quantum states of a photon. We will also discuss how basic physics principles impose fundamental limitations on sensitivity and bandwidth, and how 2D materials can aid in overcoming these limitations.
