Physicists Demonstrate Quantum Memory with Matter Qubits
(PhysOrg.com) -- For the first time, scientists have successfully operated a quantum gate between two remote particles of matter, marking an important step toward the development of a quantum computer. In previous experiments, researchers have used photons, which are difficult to store. Using matter qubits enables the researchers to store the obtained quantum information, opening up new possibilities for the generation of remote networks of entangled qubits.

Data-Taking Dress Rehearsal Proves World`s Largest Computing Grid is Ready for LHC Restart
(PhysOrg.com) -- The world`s largest computing grid has passed its most comprehensive tests to date in anticipation of the restart of the world`s most powerful particle accelerator, the Large Hadron Collider (LHC). The successful dress rehearsal proves that the Worldwide LHC Computing Grid (WLCG) is ready to analyze and manage real data from the massive machine. The United States is a vital partner in the development and operation of the WLCG, with 15 universities and three U.S. Department of Energy (DOE) national laboratories from 11 states contributing to the project.

Wagner's 'difficult' reputation unwarranted says research
The composer Richard Wagner is well-known, even notorious, for writing operas that can challenge both performers and listeners. A new study published in the Journal of the Acoustic Society of America reveals that Wagner set his text to music in a way that uses the acoustics of the soprano voice in a manner that helps both performers and listeners.

Blackest Black Ever: Ultra-thin Material Absorbs Almost 100% Of Light
It appears to be a paradox: ultra-thin material that absorbs all incident light. Nonetheless, it does exist. Researchers have demonstrated that at a thickness of 4.5 nanometer niobiumnitride (NbN) is ultra-absorbent. They have recorded a light absorption of almost 100%, while the best light absorption to date was 50%. This research brings the ideal light detector a step closer.
