Superconducting Quantum Circuits provide the possibility for creating arbitrary quantum systems on chip. Linear and nonlinear microwave resonators can be utilized as resonant cavities and artificial atoms (or spins) that interact via travelling or stationary single microwave photons. In addition, thin suspended metal membranes can vibrate with MHZ-oscillation frequencies with mechanical energy as small as a single quanta. The combination of these structures can allow us to create platforms for processing quantum information or studying the foundations of Quantum Mechanics. Because of their ease of fabrication, superconducting quantum bits (qubits) based on Josephson junctions offers an attractive approach to quantum computing. In addition, custom designed quantum systems can be created to perform quantum simulations, study the interaction of light and atoms or light and mechanical systems, or to explore the "weirdness of quantum mechanics" with real experiments. Our program seeks to explore different fields of study on one small chip. If you work in our group, you will get experience with circuit design & architecture, materials properties, fabrication processes, packaging and microwave hygiene. We are continually pushing the forefront of fundamental science and technology through our efforts. This type of work requires creativity and effort across a broad range of disciplines from atomic physics, mechancis, quantum mechanics, superconductivity, to practical electronics, precision measurements, microwave engineering, and experimental low-temperature physics. Joint efforts exist between Ray Simmonds, Joe Aumentado, and John Teufel.
