web-flowAdd documentation on OpenQASM 2 phase conventions (#10801) (#10913) * Add documentation on OpenQASM 2 phase conventions OpenQASM 2 as a language does not provide a way to specify global phases, either of operations or the entire program. The prose of the defining paper talks about the `u1` and `rz` instructions from `qelib1.inc` as having different global phases, however since the language cannot represent this, the header file defines `rz` apparently as a direct alias to `u1`. Qiskit's position has always been that we interpret `rz` as using the phase convention of `RZGate`, and `u1` uses the different convention of `PhaseGate`. This commit adds documentation to the pages on OpenQASM 2 about this difference, and includes an example of how to override Qiskit's default if the generating code (e.g. pyZX) wants to use an alternative phase convention. * Comment on the number of overrides needed Co-authored-by: Julien Gacon <gaconju@gmail.com> --------- Co-authored-by: Julien Gacon <gaconju@gmail.com> (cherry picked from commit 10461f18c) Co-authored-by: Jake Lishman <jake.lishman@ibm.com>
