Quantum Computing with Neutral Atoms

In an early Quantum Leap post back in December 2021, I wrote about the various qubits being used to drive Quantum Computers (QC) and neutral atoms didn’t make it into the post. When I revisited the QC landscape in October of last year, four neutral atom companies made the list, representing a significant advancement in that modality. There are numerous strengths to this approach, which I’ll describe in greater detail below, but to pique your interest in learning more, consider the following recent announcements by neutral atom companies:

  • Infleqtion (f/k/a ColdQuanta) completed a $110 million Series B equity round
  • Professor Alain Aspect, a co-founder of PASQAL, was awarded the 2022 Nobel Prize in Physics
  • Atom Computer had a ribbon-cutting ceremony for the opening of its new $100 million facility in Boulder, Colorado
  • QuEra’s 256-qubit Aquila QC was made available on Amazon’s Bracket, its cloud-based QC platform

Why the recent surge in jaw-dropping announcements? Why are neutral atoms seeming to leapfrog other qubit modalities? Keep reading to find out.

The table below highlights the companies working to make Quantum Computers using neutral atoms as qubits:
