Hilbert Space, Tensor Product, and Multi-Qubit

We have been working with Hilbert space and using its rules already. In this chapter, we will give a more formal definition of Hilbert space. This allows us to better understand the mathematics of constructing a larger space (more qubits) from smaller spaces (fewer qubits). We will practice how to construct a vector in a larger space from the vectors in the smaller spaces using the tensor product.
