Quantum systems, such as quantum bits (qubits), are truly unique. They can be in superposition. The quantum superposition is a complex linear combination of their basis states |0⟩ and |1⟩. Once one observes the superposition, it collapses into one of the two basis states, resulting in either 0 or 1.
