the U.S. Department of Energy (DOE) announced $71 million in funding for 25 projects in high energy physics that will use the emerging technologies of quantum information science to answer fundamental questions about the universe.

The teams at ParityQC and the University of Innsbruck have made a significant step forward in simplifying the control of quantum computers. This advancement, detailed in the recently published paper titled “Quantum Optimization with Globally Driven Neutral Atom Arrays,” represents a scalable encoding for solving complex combinatorial optimization problems with global laser addressing.

A California Institute of Technology research team reports they achieved a significant milestone using optical tweezer arrays to trap over 6,100 neutral atoms.

Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with Stanford University and the University of California – Berkeley, have developed an on-chip twisted moiré photonic crystal sensor that uses MEMS technology to control the gap and angle between the crystal layers in real time. The sensor can detect and collect detailed polarization and wavelength information simultaneously.

Now, applied physicists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have invented a new type of interferometer that allows precise control of light’s frequency, intensity and mode in one compact package.

Scientists from the RIKEN Center for Emergent Matter Science (CEMS) and collaborators have discovered a groundbreaking way to control superconductivity—an essential phenomenon for developing more energy-efficient technologies and quantum computing—by simply twisting atomically thin layers within a layered device. By adjusting the twist angle, they were able to finely tune the “superconducting gap,” which plays a key role in the behavior of these materials. The research was published in Nature Physics.

Newly achieved precise control over light emitted from incredibly tiny sources, a few nanometers in size, embedded in two-dimensional (2D) materials could lead to remarkably high-resolution monitors and advances in ultra-fast quantum computing, according to an international team led by researchers at Penn State and Université Paris-Saclay.

Scientists at Yokohama National University (YNU), in collaboration with RIKEN and other institutions in Japan and Korea, have developed a novel method to control electron distribution in molecules using ultrafast terahertz pulses.

Making a step forward in this direction, researchers led by JILA and NIST Fellows and University of Colorado Boulder physics professors Jun Ye and Ana Maria Rey—in collaboration with scientists at the Leibnitz University in Hanover, the Austrian Academy of Sciences, and the University of Innsbruck—proposed practical protocols to explore the effects of relativity, such as the gravitational redshift, on quantum entanglement and interactions in an optical atomic clock. Their work revealed that the interplay between gravitational effects and quantum interactions can lead to unexpected phenomena, such as atomic synchronization and quantum entanglement among particles. The results of this study were published in Physical Review Letters.

Researchers from Osaka University have discovered the fundamental properties of single-photon emitters at an oxide/semiconductor interface, which could be crucial for scalable quantum technology.
