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 ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, ...

Researchers at the University of Stuttgart have successfully teleported quantum states between photons from two distant light sources, marking a pivotal advance toward practical quantum repeaters.

Shattered glass does not leap back into your hand. Smoke from a match does not gather itself and crawl back inside. In ...

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 ...

Researchers demonstrate that some forms of quantum behavior can only occur via pairwise interactions, a finding that limits the number of ways in which we can reconcile quantum mechanics with ...

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

A new study suggests that gravity could quantum-entangle particles even if it remained classical.
