Quantum Technology Network (QTNet) ETH Domain

The ETH Board decided in 2023 to support with 10 million CHF existing and newly established research groups in the field of quantum science and technology at the ETH Domain. The 10 MCHF contribution to this effort is shared between ETH Zurich (4.4 MCHF), EPF Lausanne (3.4 MCHF) and PSI (2.2 MCHF).

At EPFL, the following three groups of equipment & infrastructure were acquired:

Group 1: Infrastructure equipment focused on quantum application for shared use by the EPFL quantum community of researchers: 

Three pieces of equipment have been identified and approved for purchase by a review committee with representatives of trhe EPFL quantum community, as key for research in quantum science and technology:

  1. A parallel-plate reactor reactive ion etching (RIE) apparatus (lead: Prof. Banerjee).
  2. An atomic layer deposition system (ALD)(lead: Prof. Banerjee).
  3. A UHV single chamber evaporation system for superconducting circuits (lead: Prof. Scarlino).

Group 2: Dedicated laboratory equipment for advanced experimental research on various quantum technology platforms: 

Via a competitive internal call for infrastructure equipment, launched on October 4 2023, following 12 infrastructural projects were selected to serve a series of scientific projects:

  1. Ultrafast all-optical control of quantized magnetic flux in superconducting rings – for quantum sensing and computation (DQML lab of Prof. Jotzu)
  2. Current-in-plane apparatus its operating cost for measuring tunnel junctions including Nb/Al-AlOx/Nb trilayer stacks (LPQM lab of Prof. Kippenberg)
  3. Cavity magnonics with Rare-Earth hyperfine states (LQM lab of Prof. Ronnow)
  4. Read-out and control of superconducting cavity electro electro-optics for Terahertz quantum applications – non magnetic breadboard (HYLAB lab of Prof. Benea-Chelmus)
  5. Supercontinuum laser (LANES lab of Prof. Kis)
  6. DC and RF electronics – Equipment for device and qubit operation in a dilution refrigerator (NANOLAB of Prof. Ionescu)
  7. High-Precision Assembly Platform for Integrating 1D Nanowires and 2D Layered Materials for Novel Quantum Devices (HQC lab of Prof. Scarlino)
  8. Dry etcher for superconducting thin films (HQC lab of Prof. Scarlino)
  9. Improved NV-based quantum sensing based on IR absorption in diamond nanophotonic cavities (GR-GA lab of Dr. Galland)
  10. Cryogen-free low vibration cryostat for temperature-dependent studies of bright single photon emitters (LASPE lab of Prof. Grandjean)
  11. High-precision wavelength-meter for cavity quantum electrodynamics experiments (LQG lab of Prof. Brantut)
  12. Quantum sensing – low temperature magic angle spinning NMR probe (LRM lab of Prof. Lyndon)

Group 3: access to quantum computing platforms (infrastructure as a service) by several quantum cloud providers, for shared use by the EPFL community of researchers in quantum algorithms and quantum computing; the choice includes the three major platforms, i.e., superconducting circuit, trapped-ion, and Rydberg-atom quantum computers.
