Is "wave-particle duality" simply the quantum "uncertainty principle" in disguise?
December 23, 2014
An international team of researchers has proved that two peculiar features of the quantum world previously considered distinct are different manifestations of the same thing. They found that “wave-particle duality” is simply the quantum “uncertainty principle” in disguise, reducing two mysteries to one.
The result was published December 19 in Nature Communications and inarXiv (open access).
Patrick Coles, Jedrzej Kaniewski, and Stephanie Wehner made the breakthrough while at the Centre for Quantum Technologies at the National University of Singapore.
“The connection between uncertainty and wave-particle duality comes out very naturally when you consider them as questions about what information you can gain about a system. Our result highlights the power of thinking about physics from the perspective of information,” says Wehner, who is now an Associate Professor at QuTech at the Delft University of Technology in the Netherlands./.../
