At the LHQS we’re investigating the fundamental physics and quantum information (QI) applications of systems comprised of trapped electrons, superconducting circuit based quantum bits (qubits), and color-center defects in diamond. We’re particularly interested in creating hybrid & synthetic quantum systems with novel properties and functionality by bringing together materials and devices with a variety of interacting quantum degrees of freedom.

Extremely low temperatures (T ~ 10 mK) are required to produce the exotic quantum properties that we investigate. The hybrid quantum systems are prepared using modern nano-fabrication techniques available in the Keck Micro-fabrication Facility here at MSU. Once the samples and devices are ready, we cool them down in our state-of-the-art quantum measurement lab and use a diverse set of experimental techniques to study their fascinating quantum behavior and develop methods to control their properties at the level of single quantum excitations.
