Recent advances in material science and nanotechnology have led to a proliferation of artificial atoms in solid-state materials with controllable quantum coherence and readiness of integration and scalability. In this poster, we showcase two emerging platforms for quantum applications, two-dimensional (2D) nanoelectromechanical systems (NEMS) and hexagonal boron nitride (h-BN) quantum emitters (QEs). Our analysis envisions that a unique atomically thin structure provides large displacement in the lowest energy level, leading to nonlinear NEMS qubits with a very small footprint. In the second platform, h-BN hosts optically addressable defect states at room temperature and also possess excellent mechanical properties allowing for high frequency and high quality (Q) factor mechanical resonators. Hybrid systems based on 2D NEMS with other qubits (e.g., superconducting qubits), as well as monolithic/heterogeneous integration of quantum emitters and NEMS resonators, create exciting opportunities to deliver engineerable functionalities for quantum computing, sensing, and communication.
