It works using &#8220;bits,&#8221; which are like light switches \u2014 <strong>either ON (1) or OFF (0)<\/strong>. Everything it does \u2014 from opening a photo to running YouTube \u2014 is just a long series of 0s and 1s.<\/p>\n\n\n\n<p>But some problems are so big and complex that even the fastest computers take <strong>years<\/strong> to solve.<\/p>\n\n\n\n<p>That\u2019s where <strong>Quantum Computers<\/strong> come in. They work differently. Instead of bits, they use \u201cqubits,\u201d and <strong>qubits can be ON, OFF, or BOTH at the same time<\/strong>.<\/p>\n\n\n\n<p>Crazy, right?
