class GateImplementationsLM : public Pennylane::Gates::PauliGenerator<GateImplementationsLM>¶
A gate operation implementation with less memory.
We use a bitwise operation to calculate the indices where the gate applies to on the fly.
- Template Parameters
PrecisionT – Floating point precision of underlying statevector data
