Multipartite entanglement in quantum algorithms
Dagmar Bruß, Chiara Macchiavello · Physical Review A · 2011
We investigate the entanglement features of the quantum states employed in quantum algorithms. In particular, we analyze the multipartite entanglement properties in the Deutsch-Jozsa, Grover, and Simon algorithms. Our results show that for these algorithms most instances involve multipartite entanglement.
