These are 2-body ops that are commonly-used in quantum applications. Without frontend exposure of (Rxx/XXPhase, Ryy/YYPhase, Rzz/ZZPhase), users need to write it in the decomposed form or using exp_pauli. Both results in 2 CNOT gates. This is not ideal for MPS since we want to minimize the number of 2-q gate. Hence, add a special handling in MPS for these cases.

Do we need to add these gates in the docs? |
We don't actually add any 'new' gates. I think the expression of |
