"Today's atomic clocks enable GPS systems with a positional accuracy of a few meters. With an optical atomic clock, you may achieve a precision of just a few centimeters. This improves the autonomy of vehicles, and all electronic systems based on positioning," said Prof. Minghao Qi from Purdue University

Purdue University engineers and the Indiana Department of Transportation are working to make it possible for electric vehicles, big and small, to wirelessly charge while driving on highways. Construction is in progress on a quarter-mile test bed on U.S. Highway 231/U.S. Highway 52 in West Lafayette that the team will use for testing.

"Purdue University researchers are pioneering a path forward by harnessing solar power and IoT technology for smarter irrigation," said Woongkul Matt Lee, Assistant Professor of Electrical and Computer Engineering at Purdue. "This innovation empowers farmers to control irrigation precisely, reduce energy costs, and embrace sustainable practices, marking a pivotal step in addressing modern agricultural challenges."

Tongcang Li, a professor of physics and electrical and computer engineering, leads a team that has developed the BNNTs with optically active spin qubits. "BNNT spin qubits are more sensitive to detecting off-axis magnetic fields than a diamond nitrogen-vacancy center, which is primarily sensitive to fields that are parallel to its axis, but not perpendicular," Li said. "BNNTs also are more cost-effective and offer more resilience than brittle diamond tips."

At Purdue's Video and Image Processing Laboratory, Prof. Ed Delp and a team of graduate students use powerful computers to help detect which images are fake and which are real.

"Our scheme opens a large opportunity for the adoption of deep learning-based anti-counterfeit methods in the semiconductor industry," said Alexander Kildishev, professor at Purdue University.

Nvidia played a major role in developing graphics processors, which were designed for heavy-duty calculations.

"When we say they are simpler, they are not complex; there's nuance to it," Anand Raghunathan, Silicon Valley chair professor of electrical and computer engineering at Purdue University, told Investor's Business Daily. "They are complex in the sense that the amount of computation needed is massive, it's tremendous."

Purdue University associate professor Jing Gao with the School of Engineering, who studies artificial intelligence, said AI can be used at many stages in the criminal justice system. According to Gao, who also researches the technology's trustworthiness, AI is only as good as its model creators. It uses historical data to answer questions, but historical data is rooted in bias.

In the past, experiments with these floating diamonds had trouble preventing their loss in a vacuum and reading out the spin qubits, said Tongcang Li, a professor of electrical and computer engineering and physics and astronomy professor at Purdue, in a statement. However, in our work, we successfully levitated a diamond in a high vacuum using a special ion trap. For the first time, we could observe and control the behavior of the spin qubits inside the levitated diamond in high vacuum."

Range anxiety - the fear of not making it to the next charger before the battery dies - is widely cited as a major barrier to American EV ownership. This anxiety can be lessened in two ways: increasing battery size, which also drives up vehicle cost, or adding charging locations, said Steve Pekarek, a Purdue University professor specializing in power systems for EVs.
