How Much Has Quantum Computing Actually Advanced?

Lately, it seems as though the path to quantum computing has more milestones than there are miles. Judging by headlines, each week holds another big announcement—an advance in qubit size, or another record-breaking investment: First IBM announced a 127-qubit chip. Then QuEra announced a 256-qubit neutral atom quantum computer. There’s now a new behemoth quantum computing company, “Quantinuum” thanks to the merger of Honeywell Quantum Solutions and Cambridge Quantum. And today, Google’s Sycamore announced another leap toward quantum error correction.
