Research

A lot of interesting research is going on in the Quantum Technologies group. On this page we highlight some of the exciting topics that we are working on.

This optical micrograph captures many of the research themes of the Quantum Technologies group. The device is a controlled NOT circuits for linear-optics quantum computation. Here photons are used to encode and manipulate quantum information in an integrated-photonics platform. The chip - with many of these devices -  is made using advanced nanofabrication techniques. For the detection of the single photons, superconducting single photon detectors are integrated on the same chip, and to program the quantum circuitry, optomechanical phase shifters are used. The latter are a spin-off of our other research themes: quantum optomechanics and optomechanics for science and technology.

Our research is organized around a number of central research themes: Quantum Optics, Quantum Optomechanics, Quantum Interfaces, and Optomechanics for Science & Technology. For each of these themes a subset of our core competences is used. Our expertise includes:

  • Integrated optics & photonics
  • Mechanical systems down to the nanoscale
  • Advanced nanofabrication techniques
  • Engineering and material science
  • Cryogenics
  • Vacuum technology
  • Measurement automation and data processing
  • Single photon sources
  • Superconducting single-photon detectors
  • High frequency measurements and low-noise electronics
  • Feedback, noise, and control systems
  • Modelling and simulations
  • ...

For many of these competences, decidated equipment is needed. This can be high-end commercial products, but also home-build systems. More information can be found on our Equipment page.

With our themes and competences, we cover a wide range of topics in Quantum Technology, ranging from fundamental science all the way toward technology. Hence we are always interest in both academics and industrial collaborations.
