While a <\/span><b>classic computer<\/b><span style=\"font-weight: 400;\"> uses <\/span><b>bits<\/b><span style=\"font-weight: 400;\"> to represent binary code information, a <\/span><b>quantum computer<\/b><span style=\"font-weight: 400;\"> uses <\/span><b>qubits<\/b><span style=\"font-weight: 400;\">. You <\/span><b>qubits<\/b><span style=\"font-weight: 400;\"> They have a unique characteristic called <\/span><b>overlap<\/b><span style=\"font-weight: 400;\">; Therefore, they can represent multiple states simultaneously.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This allows for <\/span><b>quantum computers<\/b><span style=\"font-weight: 400;\"> They process an impressive amount of data in parallel, providing a significant performance increase compared to classical computers. A task that would take thousands of years for conventional computers can be performed in minutes or seconds by quantum machines.<\/span><\/p>\n<h3><b>How does quantum computing work?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">To understand <\/span><b>how does it work <a href=\"https:\/\/blog.eseg.edu.br\/o-que-e-computacao-quantica\/\">quantum computing<\/a><\/b><span style=\"font-weight: 400;\"> It is necessary to understand <\/span><b>qubits<\/b><span style=\"font-weight: 400;\"> and their quantum behaviors, such as <\/span><b>overlap<\/b><span style=\"font-weight: 400;\"> e <\/span><b>quantum entanglement<\/b><span style=\"font-weight: 400;\">. Unlike traditional, non-binary bits (0 or 1), <\/span><b>qubits<\/b><span style=\"font-weight: 400;\"> They can combine their states at the same time, allowing the computer to perform several operations simultaneously, in parallel. This ability to explore multiple states makes them... <\/span><b>quantum computers<\/b><span style=\"font-weight: 400;\"> extremely powerful.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Furthermore, <\/span><b>qubits<\/b><span style=\"font-weight: 400;\"> can be intertwined by <\/span><b>quantum entanglement.
