The Max Planck–New York Center on Non-Equilibrium Quantum Phenomena has been renewed for five years, expanding its research scope with the addition of Cornell University as a partner.
New technique could enable processing speeds a million to a billion times faster than today’s computers and spur progress in many-body physics.
National Renewable Energy Laboratory researchers are tackling one of the fundamental problems in quantum information science: how to produce pure elements of quantum information—that is, those that start and remain in a well-defined “spin state”—at practical temperatures.
Information in computers is transmitted through semiconductors by the movement of electrons and stored in the direction of the electron spin in magnetic materials. To shrink devices while improving their performance—a goal of an emerging field called spin-electronics (“spintronics”)—researchers are searching for unique materials that combine both quantum properties.
A multi-institutional effort that includes researchers from Argonne, Lawrence Berkeley, and Oak Ridge National Laboratories is now underway to prepare QMCPACK for deployment on forthcoming, GPU-powered exascale machines, including the ALCF’s Aurora supercomputer. The greatly expanded computational power and parallelism of exascale will enable predictive capabilities far beyond the capacity of QMCPACK’s current implementation.
Pablo Jarillo-Herrero, the Cecil and Ida Green Professor of Physics at MIT, has received the 2021 Max Planck-Humboldt Research Award from the Max Planck Society and the Alexander von Humboldt Foundation for his work on two-dimensional quantum materials.
A team led by the Department of Energy’s Oak Ridge National Laboratory has found a rare quantum material in which electrons move in coordinated ways, essentially “dancing.” Straining the material creates an electronic band structure that sets the stage for exotic, more tightly correlated behavior – akin to tangoing – among Dirac electrons, which are especially mobile electric charge carriers that may someday enable faster transistors. The results are published in the journal Science Advances.
Riverlane has been awarded the first contract to supply quantum software to the UK’s National Quantum Computing Centre (NQCC). The NQCC, funded through UK Research and Innovation, is dedicated to accelerating the development of quantum computing in the UK.
Scientists have developed a means to create a new type of memory, marking a notable breakthrough in the increasingly sophisticated field of artificial intelligence.
The laws of quantum physics rule the microcosm. They determine, for example, how easily electrons move through a crystal and thus whether the material is a metal, a semiconductor or an insulator. Quantum physics may lead to exotic properties in certain materials: In so-called topological insulators, only the electrons that can occupy some specific quantum states are free to move like massless particles on the surface, while this mobility is completely absent for electrons in the bulk.
