Unitary time evolution
... There are infinitely many possible two-bit gates; but in practice such unitaries are difficult to do. Fortunately, it turns out that just the CNOT (or almost any other two-bit gate), together with one-bit gates, can be used to build up any unitary. (We will prove this later in the class!) When we co ...

Manifestly Covariant Functional Measures for Quantum Field Theory
... inequivalent measures is consistent with Toms’ argument that field theory is not a straightforward limit of the finite dimensional case. By expanding fields in a covariant mode expansion, we compare the measures obtained from uniform discretization in coordinate distances and from uniform discretiza ...
