Control Systems

The researchers built a system (circuit diagram on the left) that can be controlled by microwave pulses (wiggly arrow) to turn on or off different operations. This system creates a special quantum state (cubic phase state) useful for fixing errors in quantum computers. The blue areas on the right show a unique property (Wigner negative regions) that proves this state is truly quantum.

Breakthrough may clear major hurdle for quantum computers

Researchers from MIT and Stanford University created a machine-learning method that can derive a controller for a robot, drone, or autonomous vehicle that is more effective at following a stable trajectory than other methods. This technique could help, for instance, a drone to closely follow a downhill skier despite being buffeted by strong winds. Credits:Image: MIT News, with figures from iStock
