This is what Google's new development means for the fueld of quantum computing.
Google recently unveiled a new quantum computer called willow, and with it they’ve achieved some cool results.
Basically here are all the steps you need to accomplish to build a useful quantum computer, this is a useful quantum computer here, we’re not there yet, google just made the step from here to here.
That’s a really cool step because it means that they can now do this thing called error correction.
The building blocks of quantum computers are qubits, but these qubits drift away from doing what they should do; it's an unavoidable property of quantum systems called decoherence.
So to make a useful quantum computer you have to keep nudging the qubits back into coherence, that’s called error correction, and it’s really hard to do. So this is a really cool achievement, and it means they can start working on the next steps.
But I should be clear, this quantum computer is not breaking encryption or solving any useful real world problems yet, to do anything useful you need to get to the end of these steps and each of these stepping stones is a huge engineering challenge.
