Physicists say quantum mechanics may not need imaginary numbers after all
Physicists are re-evaluating the necessity of imaginary numbers in quantum mechanics, a framework long considered essential for describing atomic-scale phenomena. New research suggests that the mathematical foundations of quantum theory might be reformulated using only real numbers.
Why it matters
Challenging the fundamental mathematical requirements of quantum mechanics could lead to a deeper understanding of physical reality and potentially impact future quantum computing technologies.
Quantum mechanics is the branch of physics that explains how matter and energy behave at the atomic and sub atomic scale. Developed in the early 1900s by pioneers including Max Planck, Niels Bohr, Werner Heisenberg, and Erwin Schr dinger, it has become one of the most successful scientific theories ever created.
The theory accurately describes a wide range of microscopic phenomena. These include the famous double slit experiment, in which particles also display wave like behavior, and quantum tunneling, where particles have a probability of passing through a barrier even when they do not have enough energy to overcome it in the classical sense. Other key quantum effects, such as entanglement and coherence, now form the foundation of emerging technologies including quantum computing and quantum communication.
