An acousto-optic modulator based bi-frequency interferometer for quantum technology
Wenqi Li, Qiqi Deng, Xueshi Guo +1
We demonstrate a high performance AOM based bi-frequency interferometer, which can realize either beating or beating free interference for single photon level quantum state. Visibi…
