Quantum Entanglement Just Put the Standard Model to a New Test

Scientists from the BESIII Collaboration have used quantum entanglement to perform a new test of the Standard Model.

By studying decaying Lambda hyperons, they precisely measured how often a strange quark transforms into an up quark, providing a new test of the CKM matrix. The results agree with theory and revive a technique that could reveal cracks in our current understanding of particle physics.
