Qubits can exist simultaneously in both states due to a phenomenon known as superposition. This ability to occupy multiple states allows quantum computers to perform complex calculations at unprecedented speeds.

Another key feature of quantum computing is entanglement, which occurs when qubits become interlinked and the state of one qubit can depend on the state of another, even when they are separated by large distances. This interconnection enables quantum computers to solve problems that are computationally infeasible for classical machines, particularly in fields such as cryptography, optimization, and drug discovery. The mathematical models that govern quantum systems form a stark contrast to the deterministic nature of classical logic, reflecting a more probabilistic approach to processing information.
