In this paper I argue that entanglement is a necessary component for anyexplanation of quantum speedup and I address some purported counter-examplesthat some claim show that the contrary is true. In particular, I address Bihamet al.'s mixed-state version of the Deutsch-Jozsa algorithm, and Knill &Laflamme's deterministic quantum computation with one qubit (DQC1) model ofquantum computation. I argue that these examples do not demonstrate thatentanglement is unnecessary for the explanation of quantum speedup, but thatthey rather illuminate and clarify the role that entanglement does play.
