“Twisted” X-ray beams carrying orbital angular momentum hold great promise for imaging and probing materials at the nanoscale. Scientists have now developed and demonstrated a new technique that uses a special patterned array of engineered nanoscale magnets called an artificial spin ice to impart OAM to X-ray beams. The beams can be switched on and off using changes in temperature and magnetic fields.

Moiré patterns can occur when scientists stack two-dimensional crystals with mismatched atomic spacings. Moiré superlattices display exotic physical properties that are absent in the layers that make up the patterns. Researchers have discovered a new property in the moiré superlattices formed in tungsten diselenide/tungsten disulfide crystals, in which the electrons “freeze” and form an ordered array.

Excitons are drawing attention as possible quantum bits (qubits) in tomorrow’s quantum computers and are central to optoelectronics and energy-harvesting processes. However, these charge-neutral quasiparticles, which exist in semiconductors and other materials, are notoriously difficult to confine and manipulate. Now, for the first time, Berkeley Lab researchers have created and directly observed highly localized excitons confined in simple stacks of atomically thin materials. The work confirms theoretical predictions and opens new avenues for controlling excitons with custom-built materials.

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

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
