Quantum phononics with 2D materials

This PhD will develop a device for coupling light (photons), matter (spins) and motion (phonons) using transition-metal-dichalcogenide (TMD) monolayers. Such a device would provide the basic building block for preparing and controlling arbitrary quantum states of phonons; enabling different quantum systems to be connected via a phonon bus - overcoming a major problem facing the implementation of quantum-based computing and implementing quantum-assisted force sensing. The student will aim to develop freely suspended TMD mechanical oscillators (MOs) with high mechanical quality-factors (a vital pre-requisite for creating phonons with high quantum coherence) and probe their mechanical properties. This would open up the unique and exciting prospect of coupling phonons with optically active quantum emitters (these are essentially "artificial atoms") hosted within TMDs that the group has been recently exploring.
