Dr. Lupascu is an experimental physicist interested in the quantum dynamics of various types of physical systems and the application of quantum effects to build new types of detectors and quantum information processors. His Superconducting Quantum Device lab focuses on experimental research with superconducting devices, ranging from quantum bits for quantum information experiments, to superconducting resonators for loss characterization, among other projects.
Dr. Lupascu and his research group investigate quantum effects in solid state devices. The physical systems we are primarily interested in consist of nanostrucutured superconductors with Josephson junctions. With proper design and experimental control, these systems behave as artificial atoms. We are interested in using superconducting quantum devices as quantum bits (or qubits), which are the basic units of quantum information processors. In addition, we use the strong interaction between superconducting devices and eletromagnetic fields to explore new phenomena in quantum optics and quantum measurement with applications to amplification and sensing.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land promised to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
