Currently, there are many qubit technologies vying for sway in quantum computing. So far, superconducting (IBM, Google) and trapped ion (IonQ, Quantinuum) have dominated the conversation. Microsoft’s proposed topological qubit, which relies on the existence of a still-unproven particle (Majorana), may be the most intriguing. Recently, neutral atom approaches have quickened pulses in the quantum community. Advocates argue the technology is inherently more scalable, offers longer coherence times (key for error correction), and they point to proof-of-concept 100-qubit systems that have already been built.
