Another key property of qubits is entanglement, a uniquely quantum phenomenon that defies classical understanding. When two qubits become entangled, their states are interconnected—meaning the state of one qubit directly affects the state of the other, regardless of the distance between them. If you measure one entangled qubit, you instantly know the state of the other, no matter how far apart they are. This property creates a powerful advantage in quantum computations by allowing qubits to work together in ways that classical bits cannot.
Quantum computing holds immense potential because it can solve problems that are currently too complex or time-consuming for classical computers. Due to the superposition and entanglement of qubits, quantum computers can perform many calculations at once. This ability opens the door to revolutionizing fields like:
