Best of Last Week—Breakthroughs in quantum computing, a very tough glass and the ‘quiet’ epidemic killing US men

(—It was a very good week for physics as researchers took two big steps toward quantum computing—in the first, a team from Austria proved that complex quantum states in photons can be preserved, even in turbulent atmospheric systems, and in the other, the same team demonstrated an example of entanglement over a distance of 143 kilometers. Also a team with members from Austria, France and Australia described a quantum process that demonstrated superposition of ordered events—and thus causal nonseparability. And another team working at the Relativistic Heavy Ion Collider in the U.S. found a way to measure the force that makes antimatter stick together. Also, a new dimension to high-temperature superconductivity was discovered by a team at the U.S. DoE’s SLAC National Accelerator Laboratory. —> Read More
