**Context:** Currently, PSWAP does not have a custom implementation within PennyLane-Lightning. This results in it using the implementation from PennyLane-Core whenever the gate is used. By implementing the gate directly in PennyLane-Lightning, performance of the PSWAP gate can be improved. **Description of the Change:** Implements the PSWAP gate natively in lightning-qubit. **Benefits:** On a quick benchmark that runs O(10k) PSWAP gates on 20 qubits, the native implementation reduces execution time from ~9.0s to ~2.3s. **Possible Drawbacks:** **Related GitHub Issues:** #976: PSWAP gate implementation in Lightning Qubit [sc-77445] --------- Co-authored-by: ringo-but-quantum <[email protected]>
**Context:** PSWAP does not have a custom implementation within Lightning-Kokkos. This results in it using the implementation from PennyLane-Core whenever the gate is used. By implementing the gate directly in Lightning-Kokkos, performance of the PSWAP gate can be improved. **Description of the Change:** Implements the PSWAP gate natively in Lightning-Kokkos. **Benefits:** **Possible Drawbacks:** **Related GitHub Issues:** [sc-85797] --------- Co-authored-by: ringo-but-quantum <[email protected]>
**Context:** PSWAP does not have hooks within Lightning-GPU This results in it using the implementation from PennyLane-Core whenever the gate is used. By implementing the gate directly in Lightning-GPU, performance of the PSWAP gate can be improved. **Description of the Change:** Implements the PSWAP gate natively in Lightning-GPU. **Benefits:** **Possible Drawbacks:** **Related GitHub Issues:** [sc-85802] --------- Co-authored-by: ringo-but-quantum <[email protected]>
**Context:** Currently, the implementation of PSWAP does not contain its generators, and the gate is not differentiable. **Description of the Change:** Implements generators for the PSWAP gate. **Benefits:** **Possible Drawbacks:** **Related GitHub Issues:** [sc-86524] --------- Co-authored-by: ringo-but-quantum <[email protected]>

Context:
Currently, PSWAP does not have a custom implementation within PennyLane-Lightning. This results in it using the implementation from PennyLane-Core whenever the gate is used. By implementing the gate directly in PennyLane-Lightning, performance of the PSWAP gate can be improved.
Description of the Change:
Implements the PSWAP gate natively in Lightning-Qubit, Lightning-Kokkos, and Lightning-GPU, along with the generators for the PSWAP gate.
Benefits:
Native implementation of the PSWAP gate provides significant performance benefits on all tested PennyLane-Lightning backends. The charts below show the execution time of circuits each containing 200 PSWAP gates on varying number of qubits, as well as the realized speedup from the native implementation.
NOTE The Lightning-Qubit backend was run with the dispatcher turned off to avoid any differences in speedup coming from running AVX kernels in the original version of the code.
Benchmarks for a constant number of PSWAPS:
Benchmarks for a dynamic number of PSWAPS, increasing with circuit size:
