Anti-Laser Masquerading Absorber

Authors: George Rajna

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). [43] 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. [42] With enhanced understanding of this system, the Quantum Dynamics Unit aims to improve upon the industry standard for qubits – bits of quantum information. [41]
