Mapping the qubit state onto the Bloch Sphere

In quantum mechanics, a qubit is a two-level quantum system. These two quantum state could be spin up and spin down, herein denoted by the 0 and 1 kets. The quantum mechanical state can be in a superposition of 0 and 1. The Bloch sphere is a geometrical representation of the quantum state of a qubit. It is a unit sphere with the north pole representing the 0 state and the south pole representing the 1 state. The Bloch sphere provides a powerful visualization of the state of a qubit and is a powerful tool for understanding quantum mechanics and quantum computing. In this video, we will discuss the Bloch sphere representation and show how it can be used to visualize the state of a qubit and to perform calculations.
