Class Wire

The Wire class represents a single wire in a quantum circuit. They are represented in Zen as q0, q1, q2, etc. It uses the Quantum Circuit package to implement quantum gates. Some gates are documented here. See https://www.npmjs.com/package/quantum-circuit#implemented-gates for a list of all implemented gates.

Example
