Superconducting Quantum Circuits Laboratory

In the Superconducting Quantum Circuits Laboratory (SQCL), the excitations of superconducting circuits are used to explore fundamental physics and build hardware for high-performance quantum technologies. We design, fabricate and measure superconducting circuits with excitations and interactions that are optimal for quantum information processing, and engineer coherent interfaces between superconductors and other quantum platforms (e.g. semiconductors) to develop hybrid quantum technologies.


Dr Xanthe Croot is the director of the SQCL. Xanthe works with superconducting technology to build next-generation circuits for quantum computing and to explore fundamental physics.
