Researchers describe how to carry out the first experimental test of string theory in a paper published tomorrow in Physical Review Letters. String theory was originally developed to describe the fundamental particles and forces that make up our universe. The new research, led by a team from Imperial College London, describes the unexpected discovery that string theory also seems to predict the behavior of entangled quantum particles. As this prediction can be tested in the laboratory, researchers can now test string theory.

"If experiments prove that our predictions about quantum entanglement are correct, this will demonstrate that string theory 'works' to predict the behaviour of entangled quantum systems," said Professor Mike Duff FRS, lead author of the study from the Department of Theoretical Physics at Imperial College London.
