Okay - folks - another dimension to get our heads around. Superconducting quantum computers but different (even colder) tech than what e.g., IBM and Google are using.
There are various types of quantum computer in development but the approach using ultra-cold neutral atoms as qubits is unusual - it's different from the superconducting quantum computers being developed by big firms such as IBM and Google, or other projects that use charged atoms, also known as ions, instead. Superconducting quantum computers don't use individual atoms as qubits, and while those systems rely on low temperatures they are not as low as those needed for ColdQuanta's neutral atoms. "The superconducting folks are running at millikelvin… we're down to microkelvin," he explains, proudly.
