Qubits are the building blocks of quantum computers, which have the potential to revolutionize many fields of research by solving problems that classical computers can’t.

But creating qubits that have the perfect quality necessary for quantum computing can be challenging.

Researchers at the University of Wisconsin–Madison, HRL Laboratories LLC, and University of New South Wales (UNSW) collaborated on a project to better control silicon quantum dot qubits, allowing for higher-quality fabrication and use in wider applications. All three institutions are affiliated with the Chicago Quantum Exchange.

Leaked documents appear to show a little-known spyware company offering services that include Android and iOS device exploits for €8 million (roughly $8 million).

Exploit brokers and mercenary spyware providers have been in the spotlight recently, mainly due to revelations surrounding the use of the controversial Pegasus solution of Israeli company NSO Group.

One of NSO’s fairly new competitors is Intellexa, a company founded by Israeli entrepreneur Tal Dilian. The company claims on its website that it’s offering technologies that empower law enforcement and intelligence agencies to ‘help protect communities’. The company says it’s based in the EU and regulated, with six sites and R&D labs in Europe.

Today it only takes one and a half hours to make a superconducting particle accelerator at the Department of Energy’s SLAC National Accelerator Laboratory colder than outer space.

“Now you click a button and the machine gets from 4.5 Kelvin down to 2 Kelvin,” said Eric Fauve, director of the Cryogenic team at SLAC.

While the process is fully automated now, getting this accelerator, called LCLS-II, to 2 Kelvin, or minus 456 degrees Fahrenheit, took six years of designing, building, installing, and starting up an intricate system.

A tiny but important area in the middle of the brain acts as a switch that determines when an animal is willing to work for a reward and when it stops working, according to a study published Aug. 31 in the journal Current Biology.

“The study changes how we think about this particular region,” said senior author Melissa Warden, assistant professor and Miriam M. Salpeter Fellow in the Department of Neurobiology and Behavior, which is shared between the College of Arts and Sciences and the College of Agriculture and Life Sciences.

“It has implications for psychiatric disorders, particularly depression and anxiety,” Warden said.
