"So a qubit can hold up to two bits of information, and this is supposed to be exciting or earthshaking??"

"What am I missing?"

Each qubit can be in multiple states at any instant in time so your code can be following multiple branches at the same time and since the number of branches the code can be on simultaneously is based on an exponential function pretty soon (with enough qubits) the code can doing pretty much EVERYTHING all in one pass.

Or so I've been told. I haven't coded professionally for almost 10 years and even back then people were choosing up camps to be in - it's worthless techno-crap or it's the greatest thing since Cobol and will be able to break any encryption scheme in seconds.

I'm not going to fry my brain worrying about it, I figure by the time they actually get the kinks worked out of it Skynet will be running this place anyway.

If all that qbits do is give you denser data storage, it’s not that impressive at all. Data storage including solid state storage is pretty cheap nowdays, and compared to qbits which have to be kept near absolute zero, is much cheaper and simpler.

To do simultaneous operations on many data, what’s needed is not denser storage but a zillion processors, and from what I’ve read so far qbits don’t do any processing.

So I’m still missing what all the orgasms surrounding quantum computing is all about.
