Quantum Sensing: Probing biological systems in a new light
Abstract: Quantum optics has had a profound impact on precision measurements, and recently enabled probing various physical quantities, such as magnetic fields and temperature, with nanoscale spatial resolution. In my talk, I will discuss the development and application of novel quantum metrological techniques that enable the study of biological systems in a new regime. I will start with a general introduction to quantum sensing and its applications to nanoscale nuclear magnetic resonance (NMR) spectroscopy. In this context, I will discuss how we can utilize tools from single-molecule biophysics to interface a coherent quantum sensor with individual intact biomolecules, and how this could eventually pave the way towards a new generation of biophysical and diagnostic devices. In a second part, I will discuss a theoretical proposal that utilizes variational techniques to drive a dipolar interacting spin ensemble into a metrological relevant state with Heisenberg limited sensitivity.
Bio: Peter Maurer’s research interests lay at the interface of quantum engineering and biophysics. His lab at the University of Chicago uses quantum technology to develop novel sensing modalities that allow us to probe physical properties of biological systems that are not accessible by conventional technologies. Specific examples of such quantum technology includes a nanoscale magnetic field sensor that enables probing nuclear magnetic resonance spectroscopy at the scale of individual cells and diamond based temperature sensors that provide us with a tool to precisely perturbate biological systems at the nanoscale. Prior to joining the faculty at the University of Chicago, Peter completed a postdoctoral training in Steven Chu’s lab at Stanford University and a PhD in physics at Harvard University.
