So, have you heard of Google's Willow chip? 

It's a quantum computing chip that they have with 105 qubits—105 qubits on a single chip. And they have done some amazing work on error correction. 

So the way a conventional computer works is that you have a 0 bit and a 1 bit. And it's either a 0 or a 1, so it's binary. But in a quantum computing system, when the bits are not a logical bit but a quantum bit, then it can be both 0 and 1 unless you make a measurement. And this is the weird thing about quantum because you can have a superposition of states. 

But this leads to a lot of errors and Google has solved the problem of error correction. It's brilliant. 

Except, till date, none of the problems that the quantum computers have solved are useful problems. They are essentially useless. And this is from Google's own website, where they have plotted commercial relevance on the x-axis and the problem solved on the y-axis. And you can see clearly, Google knows that, till date, not a single problem that is commercially relevant or practical has been solved by quantum computing.
