One of the strangest features of physics is quantum entanglement, and scientists from the University of Glasgow have just captured the first photo demonstrating the effect. Share on Facebook (opens in ...

While the basic form of QKD enables information to be transmitted securely, it does have some weak points. One of them is ...

Cisco inserted itself into a quantum networking trial with Qunnect that integrated the former’s enterprise-grade ...

Researchers at the University of Innsbruck have shown that quantum sensors can remain highly accurate even in extremely noisy conditions. It's the first experimental realization of a powerful quantum ...

Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery of dark matter. With new approaches to measurement in the quantum realm, ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...

Secure quantum networks that use existing fiber to transmit entangled photons are a step closer to reality as three different teams in US, China and the Netherlands have figured out ways to build ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...
