Printed circuit board of a “thermodynamic computer” Normal Computing A first-of-its-kind computer can perform calculations using the random “noise” that is inherent in our world. It is built using standard commercial components and could eventually run artificial intelligence programs more efficiently than conventional computers. In conventional computers, all calculations are reduced to sequences of 1s … Read more
Couples are less likely to physically collide with others than friends are Shutterstock/Shawn.ccf Couples are less likely to physically bump into other people when walking in busy public spaces than pairs of acquaintances or work colleagues are. However, adding a child into the mix makes the group more likely to have a collision. When developing … Read more
Qunnect’s entanglement source Karmela Padavic-Callaghan In an office overlooking an old shipyard in Brooklyn, I am learning that I may have walked over some entangled quantum light on my way here. Since the previous evening, researchers at Qunnect have been sending particles of light, or photons, through a 34-kilometre-long loop of optical fibre underneath New … Read more
A simulated version of Paris where universities and telecommunication hubs are connected by a quantum communication network suggests that existing technology is already nearing the ability to create functional “quantum cities” Technology 21 November 2022 By Karmela Padavic-Callaghan Researchers recently simulated a quantum network larger than the city of Paris, France Nisian Hughes/Getty Images Soon, … Read more
A device that uses a piece of glass with little bumps on it can distinguish objects based on how they scatter light, removing the need for a camera or a computer Technology 4 November 2022 By Karmela Padavic-Callaghan The device identifies objects based on how they scatter near-infrared light Getty Images/Stone RF/stilllifephotographer A piece of … Read more
An algorithm created by AI firm DeepMind can distinguish between videos in which objects obey the laws of physics and ones where they don’t Technology 11 July 2022 By Matthew Sparkes Watching videos of objects interact helped an AI learn physics Audio und werbung/Shutterstock Teaching artificial intelligence to understand simple physics concepts, such as that … Read more
