Regardless of the answers, the era of entanglement under infinite book‐keeping is giving way to an era of entanglement under limited books, limited clocks and limited gates. And in this more realistic ...

In quantum physics, entanglement links particles across space in ways that defy logic. However, there’s a lesser-known phenomenon that’s even more intriguing than entanglement, and it’s called quantum ...

For decades, scientists have chased a bold idea: a quantum internet that sends information not through electrical signals but through the eerie, invisible bonds connecting particles of light. Now, ...

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

a When photon-pair generation is probabilistic, a two-photon interference measurement between A2 and B1 alone cannot distinguish successful events from unsuccessful ones. Therefore, additional ...

Teleportation. Imagine instantly transporting to a remote location like moving from your home to the office with no commute whatsoever. It's technology you always see incorporated in sci-fi media, ...

Researchers from the University of the Witwatersrand in South Africa, in collaboration with Huzhou University, discovered ...

Because of this deep connection, it’s often more accurate to think of entangled particles not as two separate things, but as ...

This is what fun looks like for a particular set of theoretical chemists driven to solve extremely difficult problems: Deciding whether the electromagnetic fields in molecular polaritons should be ...

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...

Science rarely hands us an image that rewires intuition as much as it satisfies curiosity. But one faint, floating ...
