New Frontiers in Imaging and Measurement

Quantum structured light is paving the way for breakthroughs in imaging and metrology. Researchers highlight significant advancements in resolution techniques, including the creation of the holographic quantum microscope, which enables detailed imaging of delicate biological samples. This technology also supports the development of highly sensitive sensors that leverage quantum correlations.

Beyond its applications in imaging and sensing, structured light can simulate complex quantum systems. These simulations allow scientists to predict molecular interactions within networks, providing valuable insights for discovering and designing new materials.Figure 1 shows How Extra Dimensions Change Light.

Two Decades of Rapid Advancement

Professor Andrew Forbes, corresponding author from the University of the Witwatersrand in Johannesburg, notes that the field has transformed dramatically over the past twenty years. “Engineering quantum states for specific purposes has accelerated recently, finally revealing the full potential of quantum structured light. Two decades ago, the available toolkit was almost nonexistent. Today, we have compact, efficient on-chip sources capable of generating and controlling quantum states.”

Despite these advances, challenges remain. “While progress has been remarkable, obstacles still exist,” says Forbes. “For instance, the distance over which structured light can effectively operate—both classical and quantum—is still limited. However, this limitation also presents opportunities, encouraging the exploration of more abstract degrees of freedom to harness.”

From Scientific Curiosity to Real-World Applications

Researcher Adam Vallés from the Optics Group at UAB’s Department of Physics says the field has reached a pivotal moment. “We are at a turning point: quantum structured light has moved beyond being a scientific curiosity to becoming a powerful tool with the potential to revolutionize communication, computing, and image processing.”

Vallés also emphasizes UAB’s leading role in the field through its collaboration with Forbes, citing internationally impactful achievements such as the stimulated teleportation of quantum information in high dimensions, the design of laser cavities capable of generating complex, high-purity states, and advances in cryptography, including the distribution of robust quantum keys even when communication channels are obstructed.
