Atom Computing

The hardest thing about quantum computing is finding hardware archi­tec­tures that will scale from today’s hundreds of qubits up to the millions of qubits needed for practical, business-relevant computation. Atom Computing is building its quantum computers around arrays of alkaline-earth metal atoms, which lack electrical charge and are therefore harder to perturb, giving them long coherence times. Focused laser light holds the neutral atoms in place and mediates control functions, with no wires required, making Atom’s systems highly scalable.
