6 steps to building the quantum computer

Sound in theory, but how will it actually happen?

Quantum computing is the nirvana state for most technical research and in the exploratory sciences – and, eventually, for all of computing.

The concept comes from quantum physics, which finds that electrons circling an atom are in multiple states at the same time – they only stop when we observe them. Similarly, a quantum bit (or qubit) can be in either a 0 and 1 state – or both at the same time.
