Phys. Rev. A 62, 032301 (2000) [4 pages]Experimental demonstration of a three-qubit quantum computation algorithm using a single photon and linear optics
Shigeki Takeuchi * Received 17 February 1999; published 3 August 2000 A quantum computer that gives us the result of a single quantum computation has been constructed. The quantum register was realized by modes and polarization of photons, and the unitary transformation was implemented with linear optics. For each quantum computation, the answer to the Deutsch Jozsa problem for any four-bit digit is given by a single-photon detection signal with a small error rate of less than 4%. ©2000 The American Physical Society
