LCs (liquid crystals) have a role in bandgap (PBG) materials. These materials enable the manipulation of photon flow, proving essential for cutting-edge circuits and quantum communication systems. The ability to modify bandgaps in time, thanks to the reconfigurability of LCs, enhances their suitability for a range of quantum applications. Studies have demonstrated that PBG materials based on LCs can effectively link nano emitters to circuits, opening up possibilities for effective interactions between light and matter in quantum technologies .
