Argonne & Univ. of Chicago: Using Quantum Computers to Simulate Quantum Materials

Research study titled "Simulating the electronic structure of spin defects on quantum computers," by Argonne National Laboratory and the University of Chicago. Abstract: "We present calculations of the ground and excited state energies of spin defects in solids carried out on a quantum computer, using a hybrid classical/quantum protocol. We focus on the negatively charged nitrogen vacancy c... » read more

Power/Performance Bits: Feb. 18

Outperforming copper Carbon nanotube-based fibers invented at Rice University have greater capacity to carry electrical current than copper cables of the same mass -- on a pound-per-pound basis -- according to new research. While individual nanotubes are capable of transmitting nearly 1,000 times more current than copper, the same tubes coalesced into a fiber using other technologies fail l... » read more
