Deterministic generations of photonic NOON states in cavities via shortcuts to adiabaticity
Jingwei Chen, L. F. Wei · Physical Review A · 2017
NOON states play an important role in quantum information processing and quantum metrology, but the fidelities of these states generated previously are limited, typically by the practically unavoidable decoherence and operational imperfections. Here, we propose an efficient scheme to generate photonic NOON states alternatively using the rapid population passage technique via the shortcut to adiabaticity (STA), rather than the usual Rabi oscillations. Since the deterministic population passages based on the STAs are insensitive to the details of the operations and can be implemented as fast as the Rabi oscillations, the fidelity of the generated NOON state could be satisfactorily high. The feasibility of the proposal is demonstrated specifically with the experimental circuit QED systems by rapidly driving two artificial qutrits.
