Scientists Revise Quantum Principles by Manipulating Light Across Time and Space

Researchers at Imperial College London have transformed the classic double-slit experiment into a groundbreaking time-based study, exploring the behavior of light in unprecedented ways. Led by Professor Riccardo Sapienza, the team utilized lasers to modify the optical properties of a thin film of indium-tin-oxide in femtoseconds—allowing them to witness light’s frequency changes over time instead of space. Their findings, published in Nature Physics, reveal a new dimension of light’s dual nature and open avenues for innovative applications, such as advanced spectroscopy, telecommunications, and medical imaging. This research could lead to faster data transmission, more effective cancer treatments, and even new forms of “time crystals.” Overall, the study not only enhances our understanding of quantum mechanics but also heralds a new era of technological advancements across multiple sectors.
