Abstract
We describe the construction of a conditional quantum control-NOT (CNOT) gate from linear optical elements following the program of Knill, Laflamme, and Milburn [Nature 409, 46 (2001)]. We show that the basic operation of this gate can be tested using current technology. We then simplify the scheme significantly.
