Part 3/8:
In contrast, quantum computers employ qubits, units that leverage the principles of quantum mechanics. For instance, if a classical computer navigates a maze by testing each pathway sequentially, a quantum computer can analyze all possible paths simultaneously through a quantum state called "superposition."
Remarkably, qubits exist in multiple states simultaneously until they are observed. At that moment, the superposition collapses into a definitive state, enabling powerful calculations. The more qubits that are entangled, the wider the range of computations that can be undertaken. Two qubits can represent four possible values while a 20-qubit system can symbolize over a million.
