class GateImplementationsPI : public Pennylane::LightningQubit::Gates::PauliGenerator<GateImplementationsPI>¶
Kernel functions for gate operations with precomputed indices.
For given wires, we first compute the indices the gate applies to and use the computed indices to apply the operation.
- Template Parameters
PrecisionT – Floating point precision of underlying statevector data.
