For a future quantum internet to work, scientists need to perfect a quantum repeater that can send information over long ...

Quantum communication is edging closer to reality thanks to a breakthrough in teleporting information between photons from ...

Albert Einstein and Niels Bohr had an ongoing rivalry about the true nature of quantum mechanics, and came up with a thought ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

Physicists have now teleported the quantum state of a single photon between distant quantum dots, turning a long theorized building block of the quantum internet into a working device. By reliably ...

A quiet shift is taking place in physics labs that could one day reshape how you send a message, store data, or protect ...

The famous double-slit experiment brings into question the very nature of matter. Its cousin, the quantum eraser experiment, ...

A team of physicists has uncovered a surprising new way to explore one of science's greatest challenges: uniting the two fundamental theories that explain how our universe works—Einstein's theory of ...

The proposed method uses a single rare-earth ion, trapped inside a tapered optical fiber, to directly generate and guide single photons within the fiber, representing a key low-cost component for ...

Using a technique known as a Bell state measurement, the team interfered one photon from the entangled pair with the photon from the first quantum dot. This caused the information encoded in the first ...
