Today IBM unveiled 2 new quantum computers, one called "Condor" is the
largest the company has ever made with 1121 Qubits, up from their 433 Qubit
machine that came out last year. The other machine called "Heron" only has
133 Qubits but has an error rate that is 5 ti
arily faster than the fastest of all possible classical algorithms.*
Yes nobody has proved it, nevertheless nearly every mathematician thinks
it's true and quantum computers can do things that conventional computers
can't. My intuition tells me the same thing, now that we know for sure that

What we need are not the algorithms, but the ice-cold machinery, coupled with
AI to make the quantum leap technologically. Quantum computing is said to kick
large errors along with faster processing.
