The Present and Possible Future of Quantum Computing
summary
Survey of concrete results and remaining gaps: experiments detect signatures of a Majorana zero mode in semiconductor nanowires with epitaxial aluminum, devices sit at ~10 mK on a fridge and connect to room electronics, spin-qubit dots show coherence oscillations on 10–120 ns timescales and rows of ~15 dots are controllable, a five‑qubit superconducting device claims a quantum error correction threshold, but actual braiding of non‑abelian modes remains unperformed and large‑scale fault‑tolerant machines are not yet built.
