  1. Probing Quantum Behavior in Qubit-Coupled Nanomechanical SystemsMatthew LaHaye, Syracuse University, DMR 1056423 (1a) The quantum mechanical properties of micro and nanoscale devices is now being actively studied for both fundamental pursuits (e.g. the study of quantum mechanics in hitherto unexplored macroscopic limits) and for the development of new technologies (e.g. quantum computing and quantum-assisted sensing). In the LaHaye Lab we are developing a novel quantum system that consists of three integrated micro and nanoscale devices (Figs. 1a and 1b): A superconducting circuit (Fig. 1a); a superconducting qubit (Fig. 1c); and a nanomechanical structure (Fig. 1d). This system will enable us to study issues of central importance to emerging quantum technologies, including the limits of measurement, quantum entanglement and the transition from quantum to classical behavior.

  2. Probing Quantum Behavior in Qubit-Coupled Nanomechanical SystemsMatthew LaHaye, Syracuse University, DMR 1056423 An important broader objective of Prof. LaHaye’s DMR award is to enhance students’ appreciation for and understanding of contemporary topics in quantum research through organized seminars and international collaboration. In the current year, Prof. LaHaye has continued to work toward this objective by organizing a series of lectures for graduate students at Syracuse on the subject of Quantum Dissipation. These lectures were presented by an expert in the field Prof. Amir Caldeira. Prof. Caldeira is from the University of Campinas in Brazil and is collaborating on the research outlined in Prof. LaHaye’s DMR award. Prof. LaHaye has also hosted two other international collaborators, Prof. Frederico Brito (University of Sao Paulo, IFSC) and Dr. Seung-Bo Shim (Korea Research Institute of Science and Technology). Dr. Shim will be working with the LaHaye group through April 2013, and he will be joined at Syracuse by one of his students later this year.
