    "abstract": "One of the main advantages of an optical approach to quantum computing is the\nfact that optical fibers can be used to connect the logic and memory devices to\nform useful circuits, in analogy with the wires of a conventional computer.\nHere we describe an experimental demonstration of a simple quantum circuit of\nthat kind in which two probabilistic exclusive-OR (XOR) logic gates were\ncombined to calculate the parity of three input qubits.",
