MIT researchers developed a photon-shuttling “interconnect” that can facilitate remote entanglement, a key step toward a practical quantum computer.

STMicroelectronics has introduced hardware cryptographic accelerators and associated software libraries for general-purpose and secure microcontrollers, ready for future generations of embedded systems to resist quantum attacks.

Today at its inaugural IBM Quantum Developer Conference, IBM announced quantum hardware and software advancements to execute complex algorithms on IBM quantum computers with record levels of scale, speed, and accuracy.

ORCA Computing, has announced the acquisition of the Austin, Texas-based Integrated Photonics Division of GXC. This division is known for delivering advanced photonics solutions to top U.S. commercial and government entities including the Defense Advanced Research Projects Agency (DARPA).

Quantinuum, the world’s largest integrated quantum computing company, and RIKEN, Japan's largest comprehensive research institution and home to a world-leading high-performance computing (HPC) center, have announced an agreement in which Quantinuum will provide access to Quantinuum’s highest performing H1-Series ion-trap quantum computing technology to RIKEN. Under the agreement, Quantinuum will install the hardware at RIKEN’s campus in Wako, Saitama.

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, researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) are doubling down, literally, on metasurface technology by creating a bilayer metasurface, made of not one, but two stacked layers of titanium dioxide nanostructures. Under a microscope, the new device looks like a dense array of stepped skyscrapers.

Recently, a team of researchers led by Tobias Grass from Donostia International Physics Center in San Sebastián, with the participation of ICFO and ICREA Prof. Maciej Lewenstein, as well as researchers from ETH Zurich, Université de Lyon and TU Dortmund University, has published a Colloquium in Reviews of Modern Physics where they provide a comprehensive overview of these exotic quantum simulators. They cover various platforms, namely those based on atoms, electrons and photons, highlighting both their strengths and limitations. The paper also discusses how these platforms can enable scientists investigate phenomena across a wide range of fields, from condensed matter physics to cosmology.

A study, led by the University of Portsmouth, has achieved unprecedented precision in detecting tiny shifts in light displacements at the nanoscale. This is relevant for example in the characterisation of birefringent materials and in high-precision measurements of rotations.

Scientists have long sought to unravel the mysteries of strange metals — materials that defy conventional rules of electricity and magnetism. Now, a team of physicists at Rice University has made a breakthrough in this area using a tool from quantum information science. Their study, published recently in Nature Communications, reveals that electrons in strange metals become more entangled at a crucial tipping point, shedding new light on the behavior of these enigmatic materials. The discovery could pave the way for advances in superconductors with the potential to transform energy use in the future.
