Super Computing : Meet the Qubit

What is Super Computing?

These are issues we don't have to worry about right now but they may be terms or way to do things well into the future that we may have to think about one day.
Meet the Qubit

Today’s computers store data in extremely small transistors. Each transistor can hold a single “bit” of information: a 1 or a 0. But about thirty years ago, scientists proposed a machine that could go beyond that binary, a machine that could store data in a system that obeys the seemingly magical principles of quantum mechanics. Instead of just a 1 or a 0, a “qubit” could store both at the same time, thanks to what’s called the superposition principle.

By extension, two qubits could hold four values simultaneously: 00, 01, 10, and 11. And if you keep adding qubits, you could, in theory, build a machine far more powerful than any that exists today. “These are things you can’t explain with regular logic,” says Jerry Chow, the former Yale researcher who helps oversee IBM’s quantum computing work. “Quantum computing and quantum algorithms are all about: how do you harness that?”

But that kind of ultra-powerful machine doesn’t yet exist. Qubits, you see, are slippery things. If you try to observe the state of a quantum system, it “decoheres,” falling into one state or the other. It no longer holds both a 0 and a 1. It holds only a O or a 1, like the classical computers of today. To build a true quantum computer, researchers must harness the probability that a qubit will decohere into one state versus the other.

I think it's a good idea, you would think it would get more people interested in quantum computing at an earlier age. very similar to that other video you posted Chuck with the 'backyardbrains' to get people interested in neuroscience at a hobby level.
