IIT Bombay discovers light pulse control for quantum states

Scientists at IIT Bombay found a simple way to control tiny quantum states in super-thin materials using just one light pulse.

These materials are so thin that they're only one atom thick.

Inside them, tiny particles called electrons can be in two different states, which scientists call valleys.

These valleys can be thought of as the 0 and 1 in computing.

Before this discovery, controlling these valleys was hard and needed complicated setups.

But now, the scientists showed that a single light pulse with a slight tilt can push the electrons into one valley or the other.

What's really cool is that the same light pulse also creates a tiny electric current that tells scientists which valley the electrons are in.

This makes the process easy to control and read without needing extra tools.

The method works with different types of light and doesn't need to be perfectly tuned to the material, making it very useful for future technology.
