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 ...

Scientists have successfully transmitted quantum data and conventional data through a single optical fiber for the first time. The research demonstrates that quantum data in the form of entangled ...

Quantum computers promise ultra-secure communication and extraordinary computing power, but today’s machines are bulky, ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University ...

Any time you use a device to communicate information—an email, a text message, any data transfer—the information in that ...

Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

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 ...

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 ...

With the help of a new experiment, researchers at Linköping University, among others, have succeeded in confirming a ten-year-old theoretical study, which connects one of the most fundamental aspects ...
