Build a Bound State – Coupling Quantum Dots to Superconductors

Abstract: Progress in microfabrication has allowed fabrication of highly tuneable semiconductor-superconductor heterostructures yielding new platforms to both create and manipulate subgap states. Such bound states, isolated in energy by the superconducting gap, are important building blocks for many schemes of quantum computation. In this talk I will present how bound states arise in Quantum Dot-Superconductor systems, how we can model them and what we can learn from transport measurements. Finally, I will address the complexity in experiments with double quantum dots and the physics it allows us to probe.
