Quantum leap for research into unhackable communications networks

Scientists at Heriot-Watt University in Edinburgh, Scotland, have published new research into the phenomenon known as quantum entanglement. This is when two particles—such as photons of light—remain connected even when ...

Eavesdropping on whales in the high Arctic

Whales are huge, but they live in an even larger environment—the world's oceans. Researchers use a range of tools to study their whereabouts, including satellite tracking, aerial surveys, sightings and deploying individual ...

All-optical computing based on convolutional neural networks

In a new publication from Opto-Electronic Advances the research group of Professor Xiaoyong Hu and Professor Qihuang Gong from School of Physics, Peking University, China, propose a new strategy to realize ultrafast and ultralow-energy-consumption ...

Implementing a 46-node quantum metropolitan area network

Quantum key distribution (QKD) is a method used for secure or secret key exchanges between two remote users. Using secure communication, cyberscientists ultimately aim to establish a global quantum network. Existing field ...
