Phase Gate

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.

Intuitive Interpretation

In this work, we demonstrate a new chaotic signal-induced phenomenon that the output of a chaotic signal-driven bistable system can be consistently mapped to specific logic gate operation in an optimal window of chaotic signal intensity. We term this phenomenon logical chaotic resonance (LCR). Then, an intuitive interpretation for LCR phenomenon is given based on potential well map and mean first-passage time. Through LCR mechanism, the chaotic signal with proper intensity is used to obtain reliable logical gate in the bistable system. Besides, appropriately increasing the chaotic signal intensity can effectively improve the response speed of the bistable system to the change of input signal. Finally, the role of chaotic signal in enhancing the capacity of resisting disturbance of parameters is demonstrated.
