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

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

It integrates miniature interferometers capable of generating and processing entangled photons, all while using off-the-shelf telecom components. In lab tests, the system successfully transmitted ...

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 ...

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

Researchers demonstrate that by shaping the spatial and temporal structure of photons, they can engineer customized quantum states suited for next-generation communication, sensing, and imaging ...

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

Researchers at the University of Iowa have identified a new way to "purify" photons, a development that could improve both the performance and ...

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 ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.
