We use cryogenic systems to cool our electronic devices to close to absolute zero of temperature. The photograph shows a detail of one of our setups.

Mechanically Controlled Break-Junction
To investigate devices based on single molecules electrically connected to two electrodes, we micro-fabricate gated gold break-junctions, where the thinnest (20 nm by 30 nm) section of a gold wire (yellow) is controllably broken to form a gap on the order of 1 nm for a single molecule. A side gate (blue) allows shifting the energy levels in the device.
Circuit QED Device
We investigate the quantum physical properties of electronic circuits. The photograph shows a chip made in our labs at ETH and mounted in a printed circuit board to investigate the interaction of individual photons with individual qubits.
Microwave Printed Circuit Board

The research is done by an international team including undergraduate and graduate students as well as post doctoral scientists. The lab is supported by one technician, a project manager and a secretary. (Image: Heidi Hostettler, ETH Zurich)
