Additionally, Caltech is making huge advances in two avenues of research that could produce a working quantum computer in the coming years: Machines that use neutral atoms as qubits, the quantum version of a classical bit, and those that use superconducting qubits.
Building quantum computers at large scale remains a formidable challenge. Our new image gallery provides a glimpse into the ambitious efforts required to build reliable machines. quantamagazine.org/building-…
