Manipulating the frequency-entangled states by an acoustic-optical modulator
Bao‐Sen Shi, Yun-Kun Jiang, Guang‐Can Guo · Physical Review A · 2000
In this paper, we describe how to realize conditional frequency entanglement swapping and to produce probabilistically a three-photon frequency entangled state from two pairs of frequency entangled states by using an acoustic-optical modulator. Both schemes are very simple and may be implementable in practice.
