2023 grad Ella James to continue physics studies at UAH with National Defense and Science and Engineering Fellowship

Ella James, who received a Bachelor of Science in physics from The University of Alabama in Huntsville (UAH) in spring 2023, has been awarded a National Defense and Science and Engineering (NDSEG) Fellowship, which she will use for graduate studies at UAH, a part of the University of Alabama System. “It’s three years of tuition for graduate school,” James says.

A quantum leap in computational performance of quantum processors

A project led by a group of researchers from Israel’s Bar-Ilan University, in collaboration with TII – the Quantum Research Center in Abu Dhabi, United Arab Emirates, is advancing quantum computing by improving the performance of superconducting qubits, the basic computation units of a superconducting quantum processor. The improved qubit, called a tunable superconducting flux qubit, is a micron-sized superconducting loop where electrical current can flow clockwise or counterclockwise, or in a quantum superposition of both directions.

Five Ways QSA is Advancing Quantum Computing

The Quantum Systems Accelerator has issued an impact report that details progress made since the center launched in 2020.

Researchers take a step towards turning interactions that normally ruin quantum information into a way of protecting it

Rresearchers at Aalto University in Finland and IAS Tsinghua University in China report a new way to predict how quantum systems, such as groups of particles, behave when they are connected to the external environment. Usually, connecting a system such as a quantum computer to its environment creates decoherence and leaks, which ruin any information about what’s happening inside the system. Now, the researchers developed a technique which turns that problem into its a solution.

Department of Energy Announces $9.1 Million for Research on Quantum Information Science and Nuclear Physics

Today, the U.S. Department of Energy (DOE) announced $9.1 million in funding for 13 projects in Quantum Information Science (QIS) with relevance to nuclear physics. Nuclear physics research seeks to discover, explore, and understand all forms of nuclear matter that can exist in the universe – from the subatomic structure of nucleons, to exploding stars, to the emergence of the quark-gluon plasma seconds after the Big Bang.

Quantum computers: Bar-Ilan University researchers develop superconducting flux qubits with unprecedented reproducibility

Dr. Michael Stern and co-workers from the Department of Physics and Quantum Entanglement Science and Technology (QUEST) Center at Bar-Ilan University in Israel are attempting to build superconducting processors based on a type of circuit called superconducting flux qubits. A flux qubit is a micron-sized superconducting loop where electrical current can flow clockwise or counter-clockwise, or in a quantum superposition of both directions. Contrary to transmon qubits, these flux qubits are highly non-linear objects and can thus be manipulated on very short time scales with high fidelity. The main drawback of flux qubits, however, is that they are particularly difficult to control and to fabricate. This leads to sizeable irreproducibility and has limited their use in the industry until now to quantum annealing optimization processes such as the ones realized by D-Wave.

Using a novel fabrication technique and state-of the-art equipment, a group led by Dr. Stern, in collaboration with Pr

An atomic-scale window into superconductivity paves the way for new quantum materials

Superconductors are materials with no electrical resistance whatsoever, commonly requiring extremely low temperatures. They are used in a wide range of domains, from medical applications to a central role in quantum computers. Superconductivity is caused by specially linked pairs of electrons known as Cooper pairs. So far, the occurrence of Cooper pairs has been measured indirectly macroscopically in bulk, but a new technique developed by researchers at Aalto University and Oak Ridge National Laboratories in the US can detect their occurrence with atomic precision.

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.

The crystals, also known as nanoparticles, stay charged for a long time and could benefit efforts to develop quantum computers.
