An international research team involving Paderborn University has achieved a crucial breakthrough on the road to a quantum ...

For a future quantum internet to work, scientists need to perfect a quantum repeater that can send information over long ...

Researchers at the University of Stuttgart have successfully teleported quantum states between photons from two distant light sources, marking a pivotal advance toward practical quantum repeaters.

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, ...

Quantum cryptography promises more effective protection. It makes communication secure against eavesdropping by relying on the laws of quantum physics. However, the path toward a quantum internet is ...

Team behind Purdue’s single-photon switch. Click for info. There are few technologies more fundamental to modern life than ...

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 ...

Photons weaken in optical fibers, and unlike classical light, quantum information cannot be copied or amplified. Quantum ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

Physicists have demonstrated with unprecedented accuracy that the speed of light remains constant. In 1887, a landmark physics experiment was carried out by American researchers Michelson and Morley.
