Researchers at Duke University have discovered that a perfect absorber of electromagnetic waves they described in a 2017 paper can easily be tweaked into a sort of "time-reversed laser" known as a coherent perfect absorber (CPA).  Scientists at the U.S. Department of Energy's Ames Laboratory have discovered a means of controlling the surface conductivity of a three-dimensional (3-D) topological insulator, a type of material that has potential applications in spintronic devices and quantum computing.  With enhanced understanding of this system, the Quantum Dynamics Unit aims to improve upon the industry standard for qubits – bits of quantum information.
