> - Google’s Willow quantum chip significantly outpaces current supercomputers, solving tasks in minutes that would otherwise take billions of years.
billions of years you say? Just what kinds of "computing tasks" we talkin about here?
I genuinely want to learn and figure out what is the truth and what is the best route of action when it comes to securing a portfolio.
As Google's own team report "Google will only consider itself to have created a “true” fault-tolerant qubit, once it can do fault-tolerant two-qubit gates with an error of ~10-6". That's two logical qubits.
The general consensus is that to have a practically useful quantum computer we'd need one with about a million physical Qubits. That's not just 1,000 of these 105 qubit chips because those wouldn't be entangled, but one chip with about a million entangled physical qubits and therefore 1,000 logical qubits.
