Delft University of Technology Researchers Demonstrate First Single-Phonon Directional Coupler

Researchers from Delft University of Technology and the University of Vienna have demonstrated the first 4-port directional coupler for quantum mechanical excitations, a key building block for phononic circuits. The research, published in Optica Quantum, presents a device that functions as a phononic beam splitter for single phonons, which are quantized mechanical vibrations that can […]
