The Low Temperature and Quantum Device Group seeks to probe the fundamental quantum nature of our physical world and to explore their applications in current and future technologies.
We use techniques of ultra-low temperature physics, microwave engineering, and micro- and nano-fabrication to explore the quantum properties of superconducting Josephson junctions, nanoscale devices and other quantum systems.

Quantum coherence and entanglement are essential to the rapidly evolving field of quantum Information. At low temperatures, these have been demonstrated spectroscopically in a system of two coupled artificial atoms made up of superconducting Josephson junctions. We are working to explore these quantum phenomena as we scale up to larger number of qubits.
