A team of researchers designed a two-dimensional photonic time crystal that they say could have applications in technologies like transmitters and lasers.What Is Carbon Capture? With Gizmodo’s Molly Taft | TechmodoDespite their name, photonic time crystals have little in common with time crystals, a phase of matter first proposed in 2012 and observed several years later. The fundamental commonality is that both crystals have structural patterns over time, but time crystals are quantum materials—the atoms are suspended in…

Scientists from the Technical University of Denmark in Copenhagen have achieved 1.84 petabits per second data transfers using a single photonic chip connected via a single optical fiber cable. The feat was accomplished over a distance of 7.9 km (4.9 miles). For some perspective regarding this achievement, at any time of day, the average internet bandwidth being used by the whole world’s population is estimated to be about 1 petabit/s.With the ever increasing amounts of data shifted across the internet for business, for…

The iPhone 14 delivers a 49 percent improvement in low-light performance and it's all thanks to a tweak Apple made to its Deep Fusion image pipeline. During its Far Out event on Wednesday, Apple detailed all the camera enhancements coming to the 2022 iPhone lineup, with the company's new "Photonic Engine" leading the list of improvements. When you go to take a nighttime photo with the new iPhones, Apple's Deep Fusion image processing algorithm will jump into action earlier than before, resulting in better colors and…

Scalable quantum computers and a ‘quantum internet' using silicon could be much easier to develop using existing technology, thanks to a new study by researchers at Simon Fraser University. In a major breakthrough in the development of quantum technology, the researchers describe their observations of silicon ‘T centre' photon-spin qubits. The research helps to pave the way for opportunities to create massively scalable quantum computers, as well as the infrastructure for a quantum internet, according to the…
