Arrays of strontium Rydberg atoms show promise for use in quantum computers

A team of researchers at California Institute of Technology has found that arrays of strontium Rydberg atoms show promise for use in a quantum computer. In their paper published in the journal Nature Physics, the researchers describe their study of quantum entangled alkaline-earth Rydberg atoms arranged in arrays and what they learned about them. In the same issue, Wenhui Li, with the National University of Singapore, has published a News & Views piece exploring the state of quantum computing research, and outlines the work done by the team at CIT.

Designing a flexible material to protect buildings, military personnel

Stealth technology, the idea of reducing the ability of the enemy to detect an object, has driven advances in military research for decades. Today, aircraft, naval ships and submarines, missiles and satellites are often covered with radar-absorbent material, such as paint, to hide or cloak them from radar, sonar, infrared and other detection methods. A cloak is a coating material that makes an object indistinguishable from its surroundings or undetectable by external field measurements.
