Researchers from Hanns-Christoph Nägerl’s group have produced the world’s first ultracold KCs molecules in their absolute ground state. Starting by mixing clouds of potassium and cesium atoms cooled almost to absolute zero temperature, they were able to use a combination of magnetic fields and laser beams to associate pairs of freely moving atoms into chemically […]

Over the past decades, quantum physicists and engineers have developed numerous technologies that harness the principles of quantum mechanics to push the boundaries of classical information science. Among these advances, quantum memories stand out as promising devices for storing and retrieving quantum information encoded in light or other physical carriers.

Over the past several decades, researchers have been making rapid progress in harnessing light to enable all sorts of scientific and industrial applications. From creating stupendously accurate clocks to processing the petabytes of information zipping through data centers, the demand for turnkey technologies that can reliably generate and manipulate light has become a global market […]

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like dancers following a beat.

Researchers have demonstrated that the theoretically optimal scaling for magic state distillation—a critical bottleneck in fault-tolerant quantum computing—is achievable for qubits, improving on the previous best result by reaching a scaling exponent of exactly zero.

The rapidly growing field of research on chiral phonons is giving researchers new insights into the fundamental behaviors and structures of materials. The chirality of phonons could pave the way for new methods to control material properties and to encode information at the quantum level, which has implications for, among other areas, quantum technologies, electronics, […]

Researchers have designed and demonstrated a new optical component that could significantly enhance the brightness and image quality of augmented reality (AR) glasses. The advance brings AR glasses a step closer to becoming as commonplace and useful as today’s smartphones.
