The Quantum State

A quantum state is simply a description of everything we can possibly know about a particle at a given moment. It tells you things like: where the particle is likely to be, how fast it’s moving, what energy level it’s in, what direction it’s spinning (its “spin”), and other properties that define it uniquely.

Fermions

Fermions are a class of particles that make up matter itself. Electrons, protons, and neutrons — the very things that form atoms — are all fermions. If you could zoom in on your body at the tiniest scale, everything solid about you would be made of these particles. But what makes them special isn’t just what they’re made of — it’s how they behave.
