WebJul 1, 2006 · In general, a quantum circuit is constructed with elementary gates, such as one-qubit gates and CNOT gates. It is possible, however, to speed up the execution time of a given circuit by merging those elementary gates together into larger modules, such that the desired unitary matrix expressing the algorithm is directly implemented. WebThe CNOT gate layer then copies the unitary dependencies around the qubits. The final unitary dependence picture as described in Eq. (11) shows the qubits are more independent in manipulations and measurement statistics. Fig. 4 The dependence picture of the W state.

Web2.1.2 CNOT Gate This is a quantum logic gate that acts on two qubits instead of one. One qubit acts as the control, while the other as a target; therefore, these qubits are also called control and target qubits respectively. Its purpose is to flip the state of the target qubit when the control qubit is precisely 1 . Its matrix form can be ... WebA CNOT gate can be constructed from two NS gates as shown schematically in Fig. 2A (11). Here the control and target qubits are encoded in optical mode or path (“dual-rail encoding”), with a photon in the top mode representing a logical 0 and in the bot-tom a logical 1. The target modes are combined at a 1∕2 reflec-
