Digital twin models may enhance future autonomous systems

Systems controlled by next-generation computing algorithms could give rise to better and more efficient machine learning products, a new study suggests.

Using machine learning tools to create a digital twin, or a virtual copy, of an electronic circuit that exhibits chaotic behavior, researchers found that they were successful at predicting how it would behave and using that information to control it.

Many everyday devices, like thermostats and cruise control, utilize linear controllers — which use simple rules to direct a system to a desired value...

Researchers have demonstrated how to control the “electron spin” of a nanodiamond while it is levitated with lasers in a vacuum, an advance that could find applications in quantum information processing, sensors, quantum mechanics studies, and measurement of magnetic and gravitational fields, which could be applied to computer memory and experiments to search for deviations from Newton’s law of gravitation. .
