Quantum teleportation has moved from science fiction into laboratory reality, but not in the way popular culture imagines.

Quantum entanglement has long been framed as a strange communication channel between particles, but the latest experiments ...

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 ...

Researchers at the University of Innsbruck have shown that quantum sensors can remain highly accurate even in extremely noisy ...

For decades, physicists have dreamed of a quantum internet: a planetary web of ultrasecure communications and super-powered computation built not from electrical signals, but from the ghostly ...

Create a Physics World account to get access to all available digital issues of the monthly magazine. Your Physics World account is sep ...

In this architecture, the training process adopts a joint optimization mechanism based on classical cross-entropy loss. WiMi treats the measurement probability distribution output by the quantum ...

Creating the same crystal through an alternative method could dramatically extend the reach of quantum networks, increasing ...

A new nanofabrication approach could increase the range of quantum networks from a few kilometers to a potential 2,000 km, ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. A new discovery suggests ...

Using a technique known as a Bell state measurement, the team interfered one photon from the entangled pair with the photon from the first quantum dot. This caused the information encoded in the first ...

Quantum networks are a key technology for secure communication and for Europe’s digital sovereignty. Researchers at the Karlsruhe Institute of ...
