Visualizing the Invisible Qubit Phase

The phase of a qubit is the decisive factor when we work with amplitudes. Even though we can’t measure the phase directly, it’s not invisible. We can use our simulator to visualize it. We can also use math to describe it precisely.

States with positive amplitudes

When we look at the Bloch sphere, states with a positive amplitude reside at the front-side of the X-axes and Z-axes.
