It turns out that this quantum - mechanical way of manipulating information gives quantum computers the ability to solve certain problems far more efficiently than any conceivable conventional computer. (sciencedaily.com)
For example, all electrons are spinning in a quantum mechanical way. (scientificamerican.com)
Such switches might control and stabilize crafts both in air and sea in a completely mechanical way, without the need for electrical sensors and powered control systems. (sciencemag.org)
