Quantum computing harnesses the principles of quantum mechanics to perform calculations at speeds unimaginable with traditional computers. This cutting-edge technology utilizes quantum bits, or qubits, which can exist in multiple states simultaneously, allowing for unprecedented computational power.
The Quantum Advantage
Unlike classical computers that use binary digits (bits) representing either 0 or 1, quantum computers leverage qubits that can be in a superposition of both states. This unique property, along with quantum entanglement, enables quantum computers to process vast amounts of information simultaneously, solving complex problems in minutes that might take classical supercomputers thousands of years.
