document: Reply to `` Comment on : Teleportation of an unknown state by W state '' -LSB- Phys . Lett . A 300 -LRB- 2002 -RRB- 324 -RSB- In our letter -LRB- see ibid. , vol . 296 , p. 161 -LRB- 2002 -RRB- -RRB- , the main question we consider is whether a general three-particle W state can be used to realize the teleportation of an unknown qubit state . We give the positive answer to this question in our letter , and show that W state can be used to realize to do that probabilistically . We also discuss how to do it in detail in our letter . In the previous comment -LRB- see ibid. , vol . 300 , p. 324 -LRB- 2002 -RRB- -RRB- , authors check carefully the mathematics calculation of our letter , find and point out a simple mathematics error about normalization coefficient of Eq . -LRB- 1 -RRB- . This mathematics error induces the incorrect probability calculation of Eq . -LRB- 6 -RRB- , and also an incorrect claim in first part of our letter
