We have a major effort on experimental quantum physics with superconducting circuits, but we also carry out computational and theoretical work down to fundamental quantum mechanics. Currently, we focus on control and readout techniques for superconducting qubits and on the implementation of on-demand dissipation in quantum circuits to study the related dynamics of open quantum systems.
We also develop ultrasensitive microwave detectors and on-chip components for controlling microwave photons, single-electron pumps based on silicon quantum dots, and quantum knots and monopoles in Bose-Einstein condensates. We are also proud to have given birth to a leading European quantum-computer company IQM. Recently, we jointly developed with IQM an open-source software, KQCircuits, to design superconducting quantum processors, making our tools available for the entire quantum community (more information here).

We develop fast and sensitive thermal detectors for circuit quantum electrodynamics applications.
Bose-Einstein condensation (BEC) is a manifestation of macroscopic occupation of a single quantum state.
We develop components and methodology in the rapidly growing field of quantum computing, especially in the framework of circuit quantum electrodynamics (cQED).
QCD's activities cover theoretical and computational problems in quantum information science as well as experimental realizations of quantum devices.
Our rigorous long term goal is to find a high-yield (100 pA) and metrologically accurate (10 ppb uncertainty) current source which could be used to redefine the unit of electric current, the ampere.
