Non-Abelian Gauge Fields Directly Observed for First Time

After decades of unsuccessful attempts, physicists have directly observed an exotic physical phenomenon called the non-Abelian Aharonov-Bohm effect. The findings could lead to realizations of what are known as topological phases, and eventually to advances toward fault-tolerant quantum computers. To confirm the presence of non-Abelian gauge fields, Yang et al …

Theoretical Physicists Describe New Kind of Quantum Time Order

One of the fundamental principles of quantum mechanics is quantum superposition, in which a particle exists in two or more states simultaneously. In a paper published in the journal Nature Communications, University of Queensland physicist Magdalena Zych and colleagues show that particles are not the only objects that can exist …

Quantum Supremacy Is Coming: Here’s What You Should Know

Quantum computers will never fully replace “classical” ones like the device you’re reading this article on. They won’t run web browsers, help with your taxes, or stream the latest video from Netflix. What they will do — what’s long been hoped for, at least — will be to offer a …
