WebSummary form only given. We present progress towards construction of an optical CNOT gate. The gate is predicted to perform all quantum gate operations within the standard coincidence basis paradigm and test the principles of linear optical quantum computation. The CNOT gate operates on a quantum register consisting of 2 qubits. The CNOT gate flips the second qubit (the target qubit) if and only if the first qubit (the control qubit) is . If are the only allowed input values for both qubits, then the TARGET output of the CNOT gate corresponds to the result of a classical XOR gate. Fixing CONTROL as , the TARGET output of the CNOT gate yields the result of a classical NOT gate.
