Super-Cold Cloud of Atoms Magnifies Effects of Quantum Mechanics

Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since.

Electrons in Bismuth Behave Differently to Free Electrons in Simple Metals

Time and again, even simple materials take physicists by surprise. Researchers at the Max Planck Institute for Chemical Physics of Solids in Dresden have observed an electronic property in the metal bismuth which they expected only in significantly more complex materials.

Research on Majorana Fermion Receives $3 Million Grant

University of Pittsburgh physicist Sergey Frolov has received a $3 million Office of Naval Research Basic Research Challenge grant to explore ways of transforming quantum computing through the use of an unusual particle. Frolov will be the primary investigator for the study on the Majorana fermion, a long-posited but elusive elementary particle that Frolov and colleagues discovered in 2012.

Global Symmetry Not Required for Sped up Search by Quantum Particles

A quantum particle can search for an item in an unsorted "database" by jumping from one item to another in superposition, and it does so faster than a classical computer ever could.
