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 ...

Light crossed the gap between two machines in an Oxford laboratory, and with it came a result that pushes quantum computing ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out. But new in the way they share ...

A ball tossed into the air follows a path that classical physics can track with confidence. Shrink that ball down to the size ...

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor ...

A breakthrough experiment led by a team from the University of Stuttgart in Germany brings a quantum internet a step closer, with physicists teleporting a quantum state between photons produced by ...

Researchers in Germany have taken a major step toward a practical quantum internet. A team at the University of Stuttgart has demonstrated the first transfer of quantum information between photons ...

IonQ will enhance quantum interconnects to enable communication across diverse quantum computing technologies. ・The firm linked two trapped-ion systems via photonic connections, marking the first ...

In a laboratory at Oxford University, scientists have achieved something that once seemed science fiction: they made two separate quantum computers work together as one. Instead of being connected by ...

Cisco today unveiled a prototype switch it says will significantly accelerate the timeline for practical, distributed, ...
