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.

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.

An international research team has developed a new method for the efficient coupling of terahertz waves with much shorter wavelengths, so-called spin waves. Their experiments, in combination with theoretical models, clarify the fundamental mechanisms of this process previously thought impossible. The results are an important step for the development of novel, energy-saving spin-based technologies for data processing.

Researchers have developed a new method for manipulating information in quantum systems by controlling the spin of electrons in silicon quantum dots. The results provide a promising new mechanism for control of qubits, which could pave the way for the development of a practical, silicon-based quantum computer.

In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.

With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.

Electronic gaming can precipitate life-threatening cardiac arrhythmias in susceptible children whose predisposition may have been previously unrecognized, according to a new report. The investigators documented an uncommon, but distinct pattern among children who lose consciousness while playing electronic (video) games.

'You're so smart!' -- This encouraging response may actually do more harm than good to children's math performance, according to a new study. The study found that encouraging children with responses related to their personal traits or innate abilities may dampen their math motivation and achievement over time.
