This capability allows quantum computers to handle vast amounts of data simultaneously, giving them an advantage in solving complex problems. When you scale this to multiple qubits, the number of possible states grows exponentially.
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.
