A Brief Overview of Quantum Hardware

I’ve been meaning to create a centralized reference area for different kinds of quantum hardware, so that they might be easily compared to one another. A way to make this efficient is to create it on a wiki, but that seems like too much work for what should be about 5-6 pages. So instead, I’ll use this location as a central index, and then link to different blogs with plentiful citations. Hope this works for growing my knowledge in the future!

Some links to quantum computing research groups around the world, taken from a Reddit comment that I made a few weeks ago:

For experimental superconducting groups:

For experimental trapped ion groups:

For experimental neutral atom groups:

General experimental work:

  • University of Science and Technology of China (Wei, Lu)
  • Delft University
  • UNSW

General theory work:

I think I left out most of the “related technologies” area – ie, not quantum optics, quantum sensing, etc. I think most of these people are working towards some kind of qubit technology.

Comment for me to add more groups here. I’ll try to create links to each of these group websites as well.

Key quantum hardware:

  • Quantum Superconducting Circuits (Transmon, Xmon, Flux Qubit)
  • Trapped Ions
  • Cold Atoms
  • Photonic Qubits (Flying)
  • Quantum Dots
  • Diamond Nitrogen-Vacancy Centers
  • Nuclear Magnetic Resonance (NMR)
