A quantum computer did something a classical computer just can’t do

Quantum computing still seems to be at a pretty early stage. At the same time, it looks like it has the potential to do truly remarkable things. In at least one case, it did something a classical computer just can’t feasibly do:

But that seriously understates what’s going on here. Every calculation that’s done on a quantum computer will end up being a measurement of a quantum system. And in this case, there is simply no way to get that probability distribution using a classical computer. With this system, we can get it in under 10 minutes, and most of that time is spent in processing that doesn’t involve the qubits. As the researchers put it, “To our knowledge, this experiment marks the first computation that can only be performed on a quantum processor.”

“… the whole stream is just noise”, the state of news media

The state of news media
Reading newspapers

A depressing thought from Om Malik about the state of much of the news media these days. Fortunately there are still sources of insightful analysis that is worth reading. You just have to dig a little deeper to find them.

One of the current downsides of news blogging is that we have atomized it to a point where the whole stream is just noise. In the tech industry, funding news and HR moves have been fetishized to a point where there’s no point checking anything. Companies are getting smart and spewing so much PR content that everything and anything seems all the same — important and unimportant, both at the same time.

There is a metaphorical silver lining, though:

I know one thing: there is so little context to what we read that when we find something intelligent, we actually read it, even when there are annoying banners or native ads or teeth-whitening messages.

But be sure the read Malik’s whole post. As with all of his work, it is well worth the read.
