Scientists from the UChicago and Purdue University, including Professor of Chemistry David Mazziotti, collaborated on a new technique to construct a unique “fingerprint” of the noise on a quantum computer as it is seen by a program run on the computer. This approach, they say, shows promise for mitigating the noise problem—as well as suggesting ways that users could actually turn noise to their advantage.

The Bulletin of the Atomic Scientists announced on Jan. 20 that the hands of the Doomsday Clock—which resides on campus and was started by members of the Manhattan Project—remain at 100 seconds to midnight—the closest it has ever been to apocalypse. The Bulletin cited disinformation, global security threats including ‘nuclear saber rattling,’ lack of actionable climate policies, disruptive technology and insufficient worldwide COVID-19 response.

January 12, 2022

Aided by sophisticated computational tools, the MICCoM team reaped a harvest of pivotal discoveries that should pave the way for new quantum devices.

Aided by sophisticated computational tools, the MICCoM team led by Prof. Giulia Galli reaped a harvest of pivotal discoveries that should pave the way for new quantum devices, like greatly improved control over the formation of vacancies in silicon carbide used for realizing qubits in quantum devices.

Twelve for dinner: How the Milky Way ‘ate’ smaller star clusters and galaxies

Artist’s representation of our Milky Way galaxy surrounded by dozens of stellar streams (highlighted in different colors).

Astronomers including Asst. Prof. Alex Ji are one step closer to revealing dark matter enveloping our Milky Way galaxy, thanks to a new map of twelve streams of stars orbiting within our galactic halo. Using doppler calculations, the scientists measured the speeds of stars and their chemical compositions, telling us where they were born.
