A novel quantum state, the coherent state of photonic dimers, has been introduced, with entangled two-photon states as its building blocks rather than single photons. These dimers, which are spatially correlated and frequency anti-correlated, show strong bunching behavior. Our latest research introduces a new variant, the two-color photonic dimer, and explores how it propagates through turbulent media compared to traditional light sources. We demonstrate that this quantum light source can achieve turbulence-free interferometry in its second-order intensity measurements under suitable conditions. The inherent bunching behavior of photonic dimers results in intensities significantly surpassing those of traditional light sources like lasers or thermal light. This unique property of two-color photonic dimer enhances the robustness of optical imaging techniques to atmospheric turbulence, promising for applications requiring high sensitivity and stability, such as gravitational-wave detection.
