Researchers from Caltech and the University of Southern California report the first application of quantum computing to a physics problem. By employing quantum-compatible machine learning techniques, they developed a method of extracting a rare Higgs boson signal from copious noise data.

Weak force decays change the identity of a particle as well as its electrical charge. Scientists are looking for identity-changing decays with no change in electrical charge, which would point to new physics.

Despite a century of effort, scientists have had only cursory success in describing the nature of gravity in the quantum realm. Don Lincoln talks about quantum gravity and the need to make advances in this area.

The subatomic world has long been known to be truly mind-bending, with particles that are waves and vice versa. Cats are alive and dead and everything is governed by probability.
