Abstract
If one has two independent quantum systems, with state spaces \(\mathcal H_1\) and \(\mathcal H_2\), the combined quantum system has a description that exploits the mathematical notion of a “tensor product,” with the combined state space the tensor product \(\mathcal H_1 \otimes \mathcal H_2\).
