Phys. Rev. A 48, 1687–1690 (1993)Quantum random walksReceived 1 October 1992; published in the issue dated August 1993 We introduce the concept of quantum random walk, and show that due to quantum interference effects the average path length can be much larger than the maximum allowed path in the corresponding classical random walk. A quantum-optics application is described. © 1993 The American Physical Society URL:
