Entanglement is a peculiar feature of quantum systems that makes them behave as if they were sitting directly next to each other even if they are kilometres away. Such behaviour does not occur in classical physics. Classical particles can affect each other through fields -- such as the gravitational or electromagnetic field -- but these fields propagate with… Continue reading Connecting superconducting quantum computers with light

Building the quantum internet
Do you remember your first computer? And your first internet connection? Sure, they were not as powerful as today's technology but it was something completely new and opened many possibilities. A quantum computer, ideally connected to quantum internet, must then be even more remarkable. Although it is true that algorithms for quantum computers focus on… Continue reading Building the quantum internet
