 <h3>Improvements 🛠</h3>
 
+* Added the `compute_sparse_matrix` method for `qml.ops.qubit.BasisStateProjector`.
+  [(#5790)](https://github.com/PennyLaneAI/pennylane/pull/5790)
+
 * `StateMP.process_state` defines rules in `cast_to_complex` for complex casting, avoiding a superfluous state vector copy in Lightning simulations
   [(#5995)](https://github.com/PennyLaneAI/pennylane/pull/5995)
