The Bloch Sphere is a fascinating geometric tool used in quantum mechanics to represent the state of a qubit—the basic unit of quantum information. While classical bits are either 0 or 1, qubits can exist in a superposition, blending these states in unique ways. The Bloch Sphere captures this duality by mapping every possible qubit state to a point on its surface. The north and south poles of the sphere correspond to the classical states of 0 and 1. Any other point on the surface represents a qu
