8. Faster Search plus Threatening the Foundation of Asymmetric Cryptography with Grover and Shor

Vladimir Silva1 
This chapter brings proceedings to a close with two algorithms that have generated excitement about the possibilities of practical quantum computation:
  • Grover’s search: This is an unstructured quantum search algorithm created by Lov Grover which is capable of finding an input with high probability using a black box function or Oracle. It can find an item in $$ O\left(\sqrt{N}\right) $$ steps as opposed to a classical average of ...
