A flux qubit is a micron-sized superconducting loop where electrical current can flow clockwise or counter-clockwise, or in a quantum superposition of both directions.

Soldering flux is (or at least, should be) one of the ubiquitous features of any electronics bench. It serves the purpose of excluding oxygen from a solder joint as it solidifies, and in most cases… ...

Through "superpositioning," a qubit can represent a 0, a 1, or any proportion between. This vastly increases a quantum computer's processing speed compared to today's computers.
