We propose an effective way for realizing a three quantum logic gates (NTCP gate, NTCP-NOT gate and NTQ-NOT gate) of one qubit simultaneously controlling N target qubits based on the qubit-qubit interaction. We use the superconducting qubits in a cavity QED driven by a strong microwave field. In our scheme, the operation time of these gates is independent of the number N of qubits involved in the gate operation. These gates are insensitive to the initial state of the cavity QED and can be used to produce an analogous CNOT gate simultaneously acting on N qubits. The quantum phase gate can be realized in a time (nanosecond-scale) much smaller than decoherence time and dephasing time (microsecond-scale) in cavity QED. Numerical simulation under the influence of the gate operations shows that the scheme could be achieved efficiently within current state-of-the-art technology.

We propose a method for realizing quantum logic gates and cluster states with superconducting quantum-interference devices (SQUIDs) in cavity QED via Raman transition. In this proposal, quantum logic gates and cluster states are realized by using only two lower flux states of the SQUID system and the excited state would not be excited. Therefore, the effect of decoherence caused by the levels of the SQUID system is possibly minimized.

We show that quantum logic gates, viz. the single qubit Hadamard and Phase Shift gates, can also be realized using q-deformed angular momentum states constructed via the Jordan–Schwinger mechanism with two q-deformed oscillators.
