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

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 ...

Breakthrough hints at future quantum relays and distributed architectures that could underpin next-generation networks ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

Researchers have shown that quantum signals can be sent from Earth up to satellites, not just down from space as previously ...

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 ...

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

The ability to share quantum information is crucial for developing quantum networks for distributed computing and secure communication. Quantum computing will be useful for solving some important ...

For years, physicists treated an Earth-to-space quantum uplink as a beautiful idea that nature simply would not allow. Now a ...

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 ...

Researchers are learning to flip light on and off one particle at a time, turning single photons into a controllable resource ...
