Comment on quant-ph/0506105: The modified Grover algorithm cannot speedup unsorted database search | Gui Lu Long
; | Date: |
15 Jun 2005 | Subject: | quant-ph | Abstract: | In a recent paper (quant-ph/0506105), A S Gupta, M. Gupta and A. Pathak proposed a modified Grover algorithm that would exponentially accelerate the unsorted database search problem if the number of marked items is known. If this were true, it would represent a major fundamental breakthrough in computer science, mathematics, quantum information and other related branches of sciences. However the algorithm is not valid. We will explain it in this brief comment. | Source: | arXiv, quant-ph/0506121 | Services: | Forum | Review | PDF | Favorites |
