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.

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 ...

Quantum technologies, devices and systems that operate leveraging quantum mechanical effects, could tackle some tasks more ...

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 ...

Quantum communication is edging closer to reality thanks to a breakthrough in teleporting information between photons from different quantum dots—one of the biggest challenges in building a quantum ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical effects, have the potential to outperform classical technologies in a ...

Physicists have manipulated individual particles of light, photons, under ultra-stable laboratory conditions. They split a solitary photon into two distinct lower-energy entities, observing with ...

IonQ claims to have achieved a significant quantum breakthrough, successfully demonstrating the frequency conversion of photons from visible to telecom wavelengths. The breakthrough, achieved during ...
