Tethered Robotic Sub Helps Engineers Refine Computerized Navigation, Control Systems
In a new indoor tank filled with almost 43,000 gallons of water, Johns Hopkins engineers are developing and testing computer control systems to serve as the "brains" for some of the world’s leading deep sea robotic exploration vehicles. To promote advances in underwater robotics, the Whiting School of Engineering recently constructed the circular hydrodynamics tank, 14 feet deep and 25 feet in diameter, inside a large lab space within Maryland Hall.
In the tank, researchers are testing the JHU Remotely Operated Vehicle, a small underwater robot developed at the university. Its navigation and control systems, also developed at Johns Hopkins, have recently been adapted and enhanced for use in the much larger Jason II vehicle, a new deep-sea oceanographic research robot operated by the Woods Hole Oceanographic Institution. The Johns Hopkins navigation program also has been deployed aboard the Deep Submergence Vehicle Alvin, Woods Hole’s inhabited oceanographic submersible.

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
