Which qubit is the best- The current state of the art in different
summary
Six platforms get concrete details: superconducting qubits use Josephson junctions on chips and microwaves, currently ~50–150 qubits and industry roadmaps to ~1,000; trapped ions use lasers, 10–20 high‑quality qubits now, portable chip traps aim toward ~100; neutral atoms in optical lattices report 10–200 atoms and >1,000 lattice sites demonstrated; photonic q modes sit at ~5–20 with integrated optics promising large scale; NV centers hit ~4–30 with 3‑node entanglement so far; silicon spin devices are <10 now but target 50–100. Coherence and benchmarks matter more than raw counts.
