Scientists boost quantum signals while reducing noise      (via sciencedaily.com) 

Researchers have developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum systems by an order of magnitude. Their device is the first to demonstrate squeezing over a broad frequency bandwidth of 1.75 gigahertz, nearly two orders of magnitude higher than other architectures.

Entangled atoms cross quantum network from one lab to another      (via sciencedaily.com) 

Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at the Campus Technik to the west of Innsbruck, Austria. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.

Amplified search for new forces      (via sciencedaily.com) 

In the search for new forces and interactions beyond the Standard Model, an international team of researchers has now taken a good step forward. The researchers are using an amplification technique based on nuclear magnetic resonance. They use their experimental setup to study a particular exotic interaction between spins: a parity-violating interaction mediated by a new hypothetical exchange particle, called a Z' boson, which exists in addition to the Z boson mediating the weak interaction in the standard Model.
