Quantum states are fragile and decohere quickly. This decoherence is suppressible if the quantum state can be stored in a topological variable. Microsoft’s approach to quantum computing is based on Majorana building blocks and topological superconducting nanostructures. At Microsoft Quantum Lab Delft, we bring together Microsoft researchers with PhD students, academic researchers, and Delft University of Technology employees to achieve scientific breakthroughs in the realization of a topologically protected qubit, with the goal of building a scalable quantum computer. The work in the lab encompasses the growth, fabrication, and physics of strong spin-orbit materials realized in semiconducting nanowires connected to conventional superconductors, with the aim of controlling and studying the properties of Majorana fermions.

  • Microsoft Quantum Lab Delft is a state-of-the-art Lab featuring: Dilution refrigerators, Molecular Beam Epitaxy, Cleanroom facilities & Microscopy


Dilution refrigerators

  • Dilution refrigerators – fridges are the workhorses at Microsoft Quantum Lab Delft, enabling us to perform experiments ranging from materials characterization to advanced qubit experiments. Topological superconducting nanostructures reveal their quantum properties at cryogenic temperatures.

Molecular Beam Epitaxy

  • Molecular Beam Epitaxy – our tool is a unique cluster of several chambers that allow deposition of different compound semiconductor families with a broad set of superconducting metals and dielectrics. Our aim is to grow nano- and micro- structures comprised of stacks of dissimilar materials, with the resulting heterostructures yielding new physical properties to meet the materials needs of our program.

Cleanroom facilities

  • Cleanroom facilities – in the Van Leeuwenhoek Laboratory / Kavli Nanofabrication research facility, we realize the quantum devices used in our experiments. The challenge in fabrication lies in integrating semiconductor and superconducting materials and keeping both materials and the entire device pristine. Activities related to our work in the cleanroom range from patterning and deposition to inspection and measurement.


  • Microscopy Microsoft Quantum Lab Delft is equipped with a Transmission Electron Microscopy (TEM), a Focused Ion Beam (FIB), and a Scanning Electron Microscope (SEM), supported by an array of specimen preparation equipment. We leverage these tools to provide insight into the interface quality of materials systems used for qubits.
