Engineered quantum light is set to revolutionize secure communication and computing by enabling photons to carry significantly more information. Researchers from the Universitat Autonoma de Barcelona and a global team have published a review in *Nature Photonics*, outlining advances in quantum structured light. This technology merges quantum information science with complex light patterns, allowing for the creation of high-dimensional quantum states, referred to as qudits, which surpass traditional qubits. This innovation not only increases data density but also enhances error tolerance and reduces noise in communication channels. In practical terms, these high-dimensional photons could improve the security of quantum communication and streamline quantum computing processes. For instance, structured light could simplify circuit designs and accelerate data processing, while also facilitating complex quantum state creation necessary for simulations. Researchers have also made strides in imaging and sensing—highlighted by the development of a holographic quantum microscope, which can image fragile biological samples. The ability to simulate complex quantum interactions opens new avenues for discovering materials. Professor Andrew Forbes notes that the past two decades have seen rapid progress in this field, evolving from a theoretical concept to practical applications. Despite these advancements, challenges remain, particularly regarding the distance limitations of structured light transmission. Adam Vallés emphasizes the significance of this moment in quantum structured light, which has transitioned from a scientific curiosity to a practical tool with real-world implications. The work has benefited from extensive collaboration, including support from the Catalonia Quantum Academy, highlighting the importance of partnerships in advancing quantum technology.
