Twisted 2D materials show potential for quantum computing

phys.org

Researchers at the University of Rochester have discovered that twisting two atom-thick flakes of molybdenum diselenide at high angles creates unique optical properties. This process generates excitons, which can function as qubits for quantum computing. Unlike previous studies that focused on small-angle twists of graphene, this new approach uses larger angles, up to 40 degrees. The findings show that these twisted layers can retain information when activated by light, despite molybdenum diselenide's unpredictable nature. The researchers believe this work is a significant step toward developing new quantum devices. They aim to use these artificial atoms in future quantum networks and advanced technologies, such as lasers and quantum simulations.
