| Abstract | We present a scheme to produce an entangled four-photon W-state by using linear optical elements. The symmetrical setup of linear optical elements consists of four beam splitters, four polarization beam splitters and four mirrors. A photon EPR-pair and two single photons are required as the input modes. The projection on the W-state can be made by a fourphoton coincidence measurement. Further, we show that by means of a horizontally oriented polarizer in front of one detector the W-state of three photons can be generated. PACS number:03.65.Ud, 03.67.-a, 42.50.Dv Entanglement is one of the most striking features of quantum mechanics. Entangled state of two or more particles not only provides the possibilities to test quantum mechanics against local hidden theory[1, 2], but also have practical applications in quantum information processing, such as quantum cryptography[3], quantum dense coding [4] and quantum teleportation[5]. Since the GHZ state was introduced to test quantum |
