A quantum computer utilizes quantum mechanics to perform calculations much faster than classical computers by leveraging qubits that can exist in multiple states simultaneously. This superposition property allows quantum computers to process information in a fundamentally different way than binary bits, potentially revolutionizing technology. Qubits can be entangled, influencing each other regardless of distance, leading to significantly higher computational power. Quantum computers can solve problems faster due to their ability to process multiple solutions simultaneously, a feat beyond the reach of classical computers. The unique nature of qubits and entanglement sets quantum computers apart, making them futuristic devices that do not resemble traditional computers.
