A quantum computer is a computing device that uses the phenomena of quantum mechanics (quantum superposition, quantum entanglement) to transmit and process data. A quantum computer (unlike a conventional one) operates not with bits (which can take on the value of either 0 or 1), but with qubits that have values of both 0 and 1 at the same time. Theoretically, this allows processing all possible states simultaneously, achieving a significant advantage (quantum superiority ) over ordinary compu...
