I’ve been a huge skeptic of this field for years. If anything, this summary makes me even more skeptical. The new innovations in laser grid isolated qubits sound amazing until you realize that many if not most (or all?) of those qubits aren’t actually functionally addressable in these systems. Add to that the facts that error correction will clearly require exponentially more qubits than are programmable; power requirements for cooling or lasers are outlandish and unlikely to shrink significantly; and we don’t even have all that many particularly good quantum algorithms. Worst of all, all the announcements for the past few years have been in the form of press releases talking about “plans” for new developments and “five year horizons”. Every academic article and new university QC lab is co-sponsored by a VC-funded corporation with every incentive to lie and mislead until a good exit point. This is not the behavior of a highly promising field.
