nLab entangling gate

Idea

In quantum computing and quantum information theory, an entangling gate is a quantum gate on a tensor product finite dimensional Hilbert space that can send tensor product quantum states to entangled quantum states.

Properties

For universality

Bremner et al. 2002 showed that adjoining any entangling 2-qbit gate to the set of 1-qbit gates yields a universal gate set.
