The Ledger

Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.

clear all ✕

why aren't all 5 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable

Rigetti: Adding a single qubit doubles a quantum computer's performance
“And with a quantum computer, if you have a hundred qubits and you add one more, you don't have a one percent performance increase, you double the performance. And that persists independent of the memory size. So every quantum bit you add to the system doubles,…”

Rigetti: 10nm Semiconductor Fabs Cost Tens of Billions
“The cost of building the manufacturing infrastructure, the cost of putting up a fab, To build technology at the 10 nanometer, 20 nanometer scale is, is extremely large. We're talking tens of billions of dollars now to get to the latest generation of technology…”

Rigetti: Classical supercomputers cannot simulate the exact structure of 50-atom molecules
“A small molecule with something like 50 atoms is, is, is almost impossible to compute the exact molecular structure, or the exact electronic structure.”

Rigetti: Only one or two groups had demonstrated superconducting qubits during PhD start
“When I started my PhD in I think there's one or two groups in the world that had ever built and demonstrated a superconducting qubit with a measurable coherence time.”
