Researchers from IIT Kanpur and Leiden University have developed a novel method for measuring light's orbital angular momentum, or the amount of twist.

Securing communication channels has been a long standing challenge for humans ever since early civilisations. Thanks to advances in computation, many so called 'secure' algorithms have been broken and the risk of information being in the wrong hands is at an all time high. A new study by researchers from IISc and NIT-Karnantaka has now developed an improvised version of a cryptographic algorithm based on quantum physics. This algorithm, the researchers claim, works efficiently and faster than their previous versions and allows higher data rate. They also also developing a new breed of communication devices running the improvised algorithms. These devices, the researchers claim, can be integrated into existing infrastructure, making them all the more secure.
