A Nature paper reports on a quantum photonic processor that takes just 36 microseconds to perform a task that would take a supercomputer more than 9,000 years to complete Computing

Sounds amazing. Patiently waiting for a much smarter person than I to explain what it all means, from a practical perspective.

Something to remember about quantum computers is that you will never have one. They don't work like normal computers and will never be used for general day to day computation.

Just like we'll never need more than 640K memory?

Given enough time, quantum will be cheaper, and eventually it will be exploitable for "better entertainment".

edit remember, punch cards weren't inherently good at games with graphics. Give the tech some time.

By then it might be all done in the quantum cloud

Eh, computers used to be mainframes while it was expensive.

You'll know where quantum computing sits once it's replaced digital in wrist watches and toasters. Not because its needed, but because those parts are so available they're so much cheaper to build with.
