Light-matter interaction is the underlying mechanism for measurement and control in quantum mechanics. We use superconducting circuits to realize quantum devices, where microwave photons are used for measurement, control and interaction, in a framework known as circuit-QED. Our research is at the intersection of atomic physics, condensed matter physics and quantum optics. Design and fabrication of circuits allows us to realize physical systems where the light-matter interactions are stronger than in natural systems, resulting in new phenomena and a deeper understanding of physics.
We study a range of topics from quantum computing and quantum simulations to fundamental physics. We focus on hardware improvement, problems of robust quantum control, and novel methods for encoding quantum simulations. We utilize our platform’s exquisite control and precision measurement capabilities to gain a better understanding of quantum measurements and open quantum systems. Since interaction with the environment is inevitable it is important to find control methods that are robust to the effects of the environment, or better harness this interaction to achieve control.
