Not at all well versed in the topic, but to me, we are at ENIAC stage of quantum - those few algorithms where quantum has an advantage provide a huge advantage worth a high price tag to those who need them - so this shouldn't be a real worry for some level of viability, technical concerns aside (which are not insignificant, as you point out) - but also as you highlight, 'some level of viability' is not the same as 'instant changes everywhere', so perceptions of hype-vs-reality in the general population is a different question

Quantum computing may not be all it's cracked up to be , but i 'm ok with some smart people becoming newly minted millionaires by investors with excess wealth.

Hmmm isn’t that fraud? If not legal fraud it sounds ethically very dubious. Edit: I’m specifically referring to the GP comment and not the overall discussion.

it s a form of redistribution

100%.

Why are we OK with smart people ripping anyone off? Just because investors have excess wealth it’s OK to steal from them?

Congratulations to the team. Sort of a win for quantum computing but where are the revenues and the numbers that justifies this valuation? A very risky investment into the unknown without knowing this.

SPAC is a scam, I really hope that the SEC will make an end for this frenzy soon.

Full-stack probably means they deal with all areas of QC, from theoretical research to hardware implementation.

> I thought quantum computing was still in the research phase? What's there to scale?

IMO it is still largely in the research phase, but actual quantum computers do exist. The thing to scale would be the number of physical and logical (error-corrected) qubits. Quantum error correction is difficult though, and will take a lot of work to get scalable QCs with error correction. With some of the current schemes being pursued today, the number of physical qubits per logical qubit is quite high (e.g. 17 physical per one logical in Surface-17).

> Rigetti expects to scale its quantum computers from 80 qubits in 2021, to 1,000 qubits in 2024, and to 4,000 qubits in 2026.

Is that realistic at all? From what I've read on the subject, everyone seems to have trouble scaling up.

"Full-stack" is not an official term, but it is a reasonable way to refer to "working on both creating the low level hardware (e.g. transmons), the intermediate layer (error correction that makes the many physical qubits into a few reliable logical qubits), and the higher levels of algorithms for useful applications".

There is no "scalable" quantum computer in existence yet. If we can make a million qubits of quality 10x better than the ones we have now, then we will definitely be able to talk about scaling and useful applications. Today we have machines with 10s to 100s of qubits that are extremely exciting technology demonstrators, but too small and too noisy to fulfill any of the promises of quantum computing from the 90s and 00s.
