The concepts of a quantum vacuum and quantum vacuum fluctuations are still not accepted by everyone. However, a group of researchers including Christopher Wilson of the Institute for Quantum Computing have found further evidence that the two concepts are a reality. Through experiments conducted at Chalmers University of Technology, the researchers were able to probe the quantum vacuum fluctuations and not only measure their strength, but also map out their shape them.
An experiment by a team of researchers led from the University of Waterloo’s Institute for Quantum Computing (IQC) shows, for the first time, that a wave property of neutrons, Orbital Angular Momentum (OAM), can be controlled.
This newfound control of neutron OAM states means that researchers can now use neutron OAM beams to see inside materials that optical, x-ray or electron OAM beams can’t penetrate.
This control can help measure the magnetism, for example, in magnetic materials, as well as deeper probes of superconducting and chiral materials.
Scientific American, Nature, and Tor Books announce the launch of the 2015 Quantum Shorts competition. The contest encourages readers to create quantum-themed “flash fiction”: a short story of no more than 1,000 words that is inspired by quantum physics.
