Generation of <b>−</b>10.7 dB unbiased entangled states of light

2021 · Applied Physics Letters

In a continuous variable quantum key distribution (CV-QKD) system, strong Einstein–Podolsky–Rosen entangled states can significantly boost the robustness and distance for secure communication. However, an inevitable bias of two entanglement quadratures may degrade the secret …
