"Revolutionary Insights on Light Unveiled by Centuries-Old Theorem"
Originally Published 2 years ago — by SciTechDaily

Researchers at the Stevens Institute of Technology have used a 350-year-old mechanical theorem to uncover new properties of light waves. By mapping light onto a system where established mechanical equations could be applied, they found a direct correlation between a light wave's degree of non-quantum entanglement and its degree of polarization. This discovery could simplify the understanding of complex optical and quantum properties through more straightforward light intensity measurements.
