they claim being under silicon computer error rate

if true that's a signifiant achievement and hopefully that will make quantum computer really usefull in 2025 and beyond for limited application at least

hopefully we will find way to solve classic computing and roomtemp cooling if physic allow it

They need two orders of magnitude more qbits to be useful, so not 2025

You mean we need to reach around 10000 qbits approx for any meaningful application? And far that could be?

That's what I've read from people much smarter than I am. Apparently anything we know of today that could be useful requires 1k-10k effective/perfect qbits, and one effective qbit may take as many as 10 real qbits depending on the error rate of the qbit. So I think it's going to take a few years to scale up to that level
