A groundbreaking study from the Technion-Israel Institute of Technology unveils a newly discovered form of quantum entanglement in the total angular momentum of photons confined in nanoscale structures – just a thousandth the width of a human hair. This discovery could play a key role in the future miniaturization of quantum communication and computing components.

Christine Muschik, a research associate faculty member at Perimeter Institute and a professor at the University of Waterloo’s Institute for Quantum Computing, is working at the frontier of quantum computing today – using not just “qubits” that are represented as superpositions of zeros and ones, but with multi-level “qudits” that go well beyond the binary qubit realm.

UC Riverside has received a Collaborative Research and Training Award of nearly $4 million from the UC National Laboratory Fees Research Program to explore how antiferromagnetic spintronics can be used to advantage in advanced memory and computing.

The researchers, led by the University of Cambridge and the Eindhoven University of Technology, have created an organic semiconductor that forces electrons to move in a spiral pattern, which could improve the efficiency of OLED displays in television and smartphone screens, or power next-generation computing technologies such as spintronics and quantum computing.

A team of researchers from the University of Ottawa has made significant strides in understanding the ionization of atoms and molecules, a fundamental process in physics that has implications for various fields including x-ray generation and plasma physics.

Physics has a problem – their key models of quantum theory and the theory of relativity do not fit together. Now, the German Research Foundation is funding physicist Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) as part of the Heisenberg Program to develop an approach that reconciles the two theories in a problematic area. A recently published paper that was published in the Journal “Classical and Quantum Gravity” gives hope that this could work.

A team of researchers from Würzburg has for the first time experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide.

In a new study published in Physical Review Letters, JILA Fellow and University of Colorado Boulder physics professor Cindy Regal, along with former JILA Associate Fellow Jose D’Incao (currently an assistant professor of physics at the University of Massachusetts, Boston) and their teams developed new experimental and theoretical techniques for studying the rates at which light-assisted collisions occur in the presence of small atomic energy splittings. Their results rely upon optical tweezers—focused lasers capable of trapping individual atoms—that the team used to isolate and study the products of individual pairs of atoms.

Pohang University of Science and Technology (POSTECH) held an opening ceremony for the 'Quantum Angular Momentum Dynamics Research Center' on the 18th. The ceremony was attended by about 100 officials, including An Tae-kyu, head of the Natural Science Division at the National Research Foundation of Korea, and Kim Seong-keun, president of POSTECH. This center will conduct in-depth research to elucidate the mechanisms of quantum angular momentum in solid materials and will carry out research on innovative material implementation and quantum angular momentum observation technology development. This research center is led by POSTECH, with participation from Sungkyunkwan University, Korea Advanced Institute of Science and Technology (KAIST), Sogang University, Yonsei University, University of Ulsan, University of Incheon, and the National Institute of Standards and Technology.

Penn and CUNY researchers collaborated to develop a device that uses quantum principles to relay information securely—an advance that could improve encryption in critical service areas like banking and health care.
