We analyze the role played by entanglement in the dynamical evolution ofGrover's search algorithm in the space of qubits. We show that the algorithmcan be equivalently described as an iterative change of the entanglementbetween the qubits, which governs the evolution of the initial state towardsthe target state, and where the entanglement can be quantified in terms asingle entanglement monotone. We also provide a necessary and sufficientcondition for the quadratic speedup, which illustrates how the change in thebipartite entanglement of the state after each iteration determines thecorresponding increase in the probability of finding the target state. Thisallows us to reestablish from the entanglement perspective that Grover's searchalgorithm is the only optimal pure state search algorithm.
