Chaos. Time travel. Quantum entanglement. Each may play a role in figuring out whether black holes are the universe’s ultimate information scramblers.

In this episode of Relatively Certain, Chris sits down with Brian Swingle, a QuICS Fellow and assistant professor of physics at UMD, to learn about some of the latest theoretical research on black holes—and how experiments to test some of these theories are getting tantalizingly close.

State-of-the-art quantum devices are not yet large enough to be called full-scale computers. The biggest comprise just a few dozen qubits—a meager count compared to the billions of bits in an ordinary computer’s memory. But steady progress means that these machines now routinely string together 10 or 20 qubits and may soon hold sway over 100 or more.

Magnets, whether in the form of a bar, horseshoe or electromagnet, always have two poles. If you break a magnet in half, you’ll end up with two new magnets, each with its own magnetic north and south.

But some physics theories predict the existence of single-pole magnets—a situation akin to electric charges, which come in either positive or negative chunks. One particular incarnation—called the Yang monopole after its discoverer—was originally predicted in the context of high-energy physics, but it has never been observed. 

Pablo Solano, a recent graduate student with JQI Fellow and UMD physics professor Luis Orozco, has been awarded the Charles A. Caramello Distinguished Dissertation Prize. According to the official award description, the prize recognizes “original work that makes an unusually significant contribution to its discipline.” The prize is given in four broad disciplinary areas and comes with an honorarium.
