Non-unital noise adds a new wrinkle to the quantum supremacy debate

April 11, 2024

Bill Fefferman

CS PhD Student Soumik Ghosh and Assistant Professor Bill Fefferman find that random circuit sampling problems that incorporate non-unital noise do not anticoncentrate, breaking every easiness and hardness result to date.

The University of Chicago has announced the winners of its 2024 “Science as Art” contest, which highlights images of innovative scientific research from the UChicago community.

The contest drew more than 60 entries from undergraduates, graduate students, staff, alumni, postdoctoral researchers, and faculty members, showcasing everything from fossils to fly anatomy. Together, these images display the pursuit of knowledge in a new light, underscoring the beauty of intellectual exploration.

The grand-prize winner is “Peculiar Dynamics” by Computer Science PhD student Sam Everett!


Meteorites may be lost to Antarctic ice as climate warms, study says

April 11, 2024

Snowy mountains in Antarctica

In a CNN article, Geophysical Sciences postdoc Maria Valdes states that as the climate continues to warm, Antarctic rocks are sinking into the ice at an increasing rate, making many meteorites inaccessible to scientists and causing the loss of "precious time capsules that hold clues to the history of our Solar System."

Congratulations to the nine PSD graduate students who have been awarded 2024 National Science Foundation Graduate Research Fellowships! The program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based master's and doctoral degrees at accredited United States institutions.


A tantalizing ‘hint’ that astronomers got dark energy all wrong

April 5, 2024

millions of galaxies mapped using coordinate data from the Dark Energy Spectroscopic Instrument

NYT article: Scientists may have discovered a major flaw in their understanding of that mysterious cosmic force. That could be good news for the fate of the universe. Wendy Freedman praises the new survey data as "superb," and Michael Turner says the possible evidence that dark energy is not constant is the best news since cosmic acceleration was established.

Stable Diffusion XL generated these images after being fed the “nightshaded” photo of Brian Cheung

SAND Lab's Nightshade aims to help artists prevent image generators from easily reproducing their work, but the researchers behind it warn more intellectual property safeguards are needed.
