Topological Quantum: Lecture Notes
... There is a fascinating relationship between the Kauffman invariant and quantum physics. For certain types of so-called ”topological quantum systems” the amplitudes of space-time processes can be directly calculated via the Kauffman invarient. We should first comment that most of what we will discuss ...
