WebA major di culty for optical quantum computing is in realizing the entangling logic gates required for univer-sal quantum computation. The canonical example is the controlled-NOT gate (CNOT), which ips the state of a target (T) qubit conditional on a control (C) qubit being in the logical state \1". Figure 2A shows why this opera-tion is di cult. WebDec 15, 2004 · Abstract. We show how to construct a near deterministic CNOT gate using several single photons sources, linear optics, photon number resolving quantum nondemolition detectors, and feed forward. This gate does not require the use of massively entangled states common to other implementations and is very efficient on resources …
