A Lesson On How Pauli Matrices Are Used To Measure Spin Of Quantum Systems

Learning from Pauli Matrices as Spin Operators from the ground up

A 1924 photograph of Werner Heisenberg, a theoretical physicist and Nobel laureate who pioneered quantum mechanics, introduced the uncertainty principle, and developed the Heisenberg model of magnetism, which describes how quantum spins interact to produce magnetic properties (Source)

In the last lessons, we learned about the mathematics behind Pauli matrices and how they are used as Quantum gates.

If you’re new to Pauli matrices, they are a set of three matrices termed:

• Pauli-X (σ(x) or σ(1))

• Pauli-Y (σ(y) or σ(2)), and

• Pauli-Z (σ(z) or σ(3))

as shown below:

This is a lesson where we discuss how they are used in Quantum mechanics as spin operators.
