Preparation of GHZ States via Grover's Quantum Searching Algorithm
Zeng Hao-Sheng, Kuang Le-Man · Chinese Physics Letters · 2000
We propose an approach to prepare GHZ (Greenberger, Horne, Zeilinger) states of an arbitrary multi-particle system in terms of Grover's fast quantum searching algorithm. The approach can be used to produce other entangled states with various degrees of entanglement.
