Superconducting circuits for quantum technologies

  • Gianluigi Catelani

Keywords: quantum circuits, quantum bits, Josephson junctions, mesoscopic superconductivity, hybrid devices 

The ongoing second quantum revolution has already led to significant advances in many areas, from atomic to solid-state physics, and in the fabrication and control of mesoscopic circuits based on electromagnetic, mechanical, ferromagnetic or optical systems, Josephson junctions, and hybrid devices. State-of-the-art quantum devices have enabled the realization of progressively more complex quantum circuits. These circuits have not only demonstrated the basic building blocks for quantum information processing (QIP) but have also led to beautiful quantum optics experiments in the microwave frequency domain and atomic physics experiments using superconducting qubits as artificial atoms. Moreover, in these mesoscopic devices, properties such as charge, spin, or heat transport are studied at the most fundamental level. As far as QIP is concerned, three main challenges can be identified: one is to determine the best design for a qubit (in terms of coherence time, reproducibility, ease of control, etc.), the second one is to harness the properties of hybrid circuits by coupling strongly to e.g. mechanical or spin degrees of freedom, and the third one is to scale up the technology to circuits capable of testing, for example, quantum error correction algorithms or quantum simulations.


The mini-colloquium will bring together theorists and experimentalists to discussed topics including (but not limited to)

- coherence and dissipation in Josephson junctions and hybrid qubits and devices

- quantum measurement in superconducting circuits

- hybrid quantum circuits and quantum memories
