This pass supports replacements for the `cx`, `cz`, `ecr`, `swap`, `rzx`, `rxx`, `ryy` and `rzz` gates, using the following identities:: ┌───â”┌───â”┌───┠q_0: ──■── q_0: ┤ H ├┤ X ├┤ H ├ ┌─┴─┠= ├───┤└─┬─┘├───┤ q_1: ┤ X ├ q_1: ┤ H ├──■──┤ H ├ └───┘ └───┘ └───┘ global phase: 3Ï€/2 ┌──────┠┌───┠┌────â”┌─────â”┌──────â”┌───┠q_0: ┤0 ├ q_0: ─┤ S ├─┤ √X ├┤ Sdg ├┤1 ├┤ H ├ │ ECR │ = ┌┴───┴â”├────┤└┬───┬┘│ Ecr │├───┤ q_1: ┤1 ├ q_1: ┤ Sdg ├┤ √X ├─┤ S ├─┤0 ├┤ H ├ └──────┘ └─────┘└────┘ └───┘ └──────┘└───┘ Note: This is done in terms of less-efficient S/SX/Sdg gates instead of the more natural `RY(pi /2)` so we have a chance for basis translation to keep things in a discrete basis during resynthesis, if that's what's being asked for. ┌──────┠┌───â”┌──────â”┌───┠q_0: ┤0 ├ q_0: ┤ H ├┤1 ├┤ H ├ │ RZX │ = ├───┤│ RZX │├───┤ q_1: ┤1 ├ q_1: ┤ H ├┤0 ├┤ H ├ └──────┘ └───┘└──────┘└───┘ cz, swap, rxx, ryy and rzz directions are fixed by reversing their qargs order. This pass assumes that the positions of the qubits in the :attr:`.DAGCircuit.qubits` attribute are the physical qubit indices. For example if ``dag.qubits[0]`` is qubit 0 in the :class:`.CouplingMap` or :class:`.Target`. Ncód•—t¦« ¦«||_||_dS)aGateDirection pass.
