While usual gapless points that are not geometrically defective i.e. Dirac points (Left column) possess only eigenvalues within [0, 1] (Bottom Left), defective exceptional points (Right column) also ...

Researchers at Heriot-Watt University have introduced a prototype quantum network that merges two smaller networks into a single, reconfigurable eight-user system capable of routing — and even ...

Quantum theory describes events that take place on extremely short time scales. In the past, such events were regarded as 'momentary' or 'instantaneous': An electron orbits the nucleus of an atom—in ...

The program supports the government’s mission for the UK to deploy the world’s most advanced quantum network by 2035. The research was carried out by Heriot-Watt University’ ...

The emergence of quantum entanglement is one of the fastest processes in nature. Scientists show that using special tricks, this can be investigated on an attosecond scale. Scientists have managed to ...

It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's ...

Scientists have long been intrigued by strange metals—materials that don’t follow the usual rules of electricity and magnetism. Unlike familiar metals like copper or gold, which conduct electricity in ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly ...

An atom is hit by a laser pulse. One electron is ripped out of the atom, another electron is shifted into a state with higher energy. Quantum theory describes events that take place on extremely short ...
