SUMMARY The invention introduces a method for fabricating low-loss niobium Josephson junctions which enhance quantum device performance by using niobium superconductors that are separated by an aluminum oxide barrier and are encapsulated with aluminum layers to prevent… Read More
SUMMARY Data compression done by classical source coding is a crucial element of modern digital infrastructure as it enables the efficient storage and transmission of images, audio files, and videos. Protocols for quantum source coding are increasingly useful to enable more efficient storage and transmission of quantum data among emerging… Read More
SUMMARY 3D microwave cavities are advantageous platforms for quantum computation due to their lengthy coherence times and fast control of quantum states when interfaced with superconducting qubits. Fast magnetic control of these cavities is crucial in tuning frequencies and interactions of superconducting qubits to efficiently manipulate quantum states. Read More
SUMMARY Integration of quantum spins into classical electronic devices has been a major challenge. However, the ability to do so would limit spectral noise and line width broadening of emissions from solid state devices, resulting in improved device performance. The divacancy in Silicon Carbide is a recently developed defect spin… Read More
SUMMARY Cavity and circuit quantum electrodynamics systems provide unprecedented control over photonic quantum states via coupling to strongly nonlinear single emitters. The millimeter (mm) wave frequency band is of great interest for quantum devices, as high-fidelity quantum emitters—such as Rydberg atoms, molecules, and silicon vacancies—exhibit resonances in these bands. High-Q… Read More
