Theory of Precision Quantum Sensing with Levitated Optomechanics: Hybrid, Multimode and Mie systems
Abstract
Project AbstractThis proposal aims to meet the current pressing demand for precision quantum sensing of weakforces and electromagnetic fields with optically trapped nanoparticles. Since these particles are notin material contact with any substrates, they can act as very sensitive probes of electric andmagnetic fields and gravitational forces. This theoretical project intends to propose novel quantumsensing solutions with three new types of modalities that have recently been brought to the fore byongoing experiments in the field. The first system of interest is an optically trapped nanoparticlewhich contains an impurity. This impurity acts as a spin. This spin is sensitive to small magneticfields. Instead of spin, a nanoparticle can also carry excess charge (often just a single electron),which is sensitive to small electric fields. The second system of interest is a nanoparticle whichoscillates along two or more spatial directions at the same time. These particles can display themechanical equivalent of optical interference and can be used as a precision tool to measure smallforces. The third system of interest consists of particles which are larger in dimension than thewavelength of the radiation used for trapping them. The larger mass of these particles makes themmore sensitive to gravitational forces, as well as better accelerometers. Our theoreticalinvestigation of these nanosystems will advance the field of precision sensing and enablereductions in cost, weight and size of future sensor designs.
