128-qubit chip

Really random, but does anyone remember Rigetti's 128 qubit computer chip that was supposed to be released in 2019? What happened to it? Has it been released or is it delayed, maybe cancelled? Can't find anything online. "We have in the past failed to meet publicly announced milestones and may fail to meet projected technological milestones in the future. For example, in 2018, we announced that we planned to build and deploy a 128-qubit system over the subsequent twelve months, but have not to date built a 128-qubit system." https://www.sec.gov/Archives/edgar/data/1838359/000119312522113117/d200128ds1a.htm Ankaa-3 is doing pretty well but this deploys a 100-qubit chip that they test on in isolation and with arrays instead of the full chip capacity I think Theres also a shift in the paradigm happening at the moment away from NISQ. I forget what Preskill coined as the new term, but he does a good job encapsulating the current outlook Basically, from 2016-2020 we were focused on getting everyone on track for the National Quantum Initiative (NQI) and its goals. Now, give years later we still havent cracked the paradigm shift we need in the ‘leading’ modality (superconducting), so we need to shift focus a bit If there is nothing then the project simply ate shit. First rule of modern capitalism: overpromise, underdeliver. Rigetti just couldn't deliver on the 128 qubit timeline and never publicly addressed it. They set the goal in 2018 and missed it without much explanation. The industry's moved away from chasing high qubit counts anyway. Error rates matter more than raw numbers, so companies like Rigetti shifted focus to building smaller, more reliable systems. That is why their recent Ankaa work uses 100 qubits but tests them in isolation instead of maxing out capacity. right- I see. I was wondering why their projects have gotten more compact, and when this happened. Thanks CEO lies really badly. Just look at all the AI company liars.
