Lena Funcke Receives Leona Woods Lectureship Award
Lena Funcke, a theoretical physicist who conducts research at the intersection of fundamental particles, the cosmos, and quantum computing, has been named a recipient of the Leona Woods Distinguished Postdoctoral Lectureship Award by the Physics Department at the U.S. Department of Energy’s Brookhaven National Laboratory.
Magnetism Meets Topology on a Superconductor’s Surface
Scientists have found an energy band gap—an energy range where no electrons are allowed—opens at a point where two allowed energy bands intersect on the surface of an iron-based superconductor. This unusual electronic energy structure could be used for quantum information science and electronics.
Machine learning blazes path to reliable near-term quantum computers
Using machine learning to develop algorithms that compensate for the crippling noise endemic on today’s quantum computers offers a way to maximize their power for reliably performing actual tasks, according to a new paper.
Know When to Unfold ’Em: Study Applies Error-Reducing Methods from Particle Physics to Quantum Computing
Borrowing a page from high-energy physics and astronomy textbooks, a team of physicists and computer scientists at Berkeley Lab has successfully adapted and applied a common error-reduction technique to the field of quantum computing.
Scientists find evidence of exotic state of matter in candidate material for quantum computers
Using a novel technique, scientists working at the Florida State University-headquartered National High Magnetic Field Laboratory have found evidence for a quantum spin liquid, a state of matter that is promising as a building block for the quantum computers of tomorrow.
New algorithm could unleash the power of quantum computers
A new algorithm that fast forwards simulations could bring greater use ability to current and near-term quantum computers, opening the way for applications to run past strict time limits that hamper many quantum calculations.
Natural Radiation Can Interfere with Quantum Computers
Radiation from natural sources in the environment can limit the performance of superconducting quantum bits, known as qubits. The discovery, reported in the journal Nature, has implications for the construction and operation of quantum computers.
Quantum Materials Quest Could Benefit From Graphene That Buckles
Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors, according to Rutgers-led research in the journal Nature. Quantum materials host strongly interacting electrons with special properties, such as entangled trajectories, that could provide building blocks for super-fast quantum computers. They also can become superconductors that could slash energy consumption by making power transmission and electronic devices more efficient.
‘Blinking” Crystals May Convert CO2 into Fuels
Imagine tiny crystals that “blink” like fireflies and can convert carbon dioxide, a key cause of climate change, into fuels. A Rutgers-led team has created ultra-small titanium dioxide crystals that exhibit unusual “blinking” behavior and may help to produce methane and other fuels, according to a study in the journal Angewandte Chemie. The crystals, also known as nanoparticles, stay charged for a long time and could benefit efforts to develop quantum computers.
Rutgers’ Greg Moore Elected to National Academy of Sciences
Rutgers Professor Gregory W. Moore, a renowned physicist who seeks a unified understanding of the basic forces and fundamental particles in the universe, has been elected to the prestigious National Academy of Sciences. Moore, Board of Governors Professor in the Department of Physics and Astronomy at Rutgers University–New Brunswick, joins 119 other new academy members and 26 international members this year who were recognized for their distinguished and ongoing achievements in original research.
NSF CAREER Award Supports Framework for Photons as Quantum Transistors
Physicist Esther Wertz has been awarded a National Science Foundation Faculty Early Career Development Program (CAREER) award to investigate nanometer-scale metal structures that will control light at the quantum limit, one photon at a time. Her work will contribute to the creation of a single photon transistor.
How a Magnet Could Help Boost Understanding of Superconductivity
Physicists have unraveled a mystery behind the strange behavior of electrons in a ferromagnet, a finding that could eventually help develop high temperature superconductivity. A Rutgers co-authored study of the unusual ferromagnetic material appears in the journal Nature.
Creating the Heart of a Quantum Computer: Developing Qubits
