Qiskit quantum gate documentation by IBM
ID: qiskit-quantum-gate-documentation-by-ibm
Official IBM Quantum mathematical gate documentation, inspected 2026-10-31. Basis order and software endianness are stated on individual pages; abstract gate actions in the wiki declare their control and target labels explicitly.
CXGate: controlled-X action and matrix
SwapGate: state exchange
CCXGate: Toffoli controls and target
HGate: computational and plus/minus bases
ControlledGate: control labels and conditional unitary
GraphState: mathematical construction by controlled-Z gates
