Rydberg Atom Arrays with Programmable Openness - Quantum Many-Body Systems

Learn about cutting-edge developments in quantum science through this technical lecture exploring Rydberg atom arrays and their applications in quantum computing. Dive into the innovative use of alkaline earth atoms, particularly ytterbium-171, for implementing programmable openness in quantum circuits. Explore how mid-circuit measurements and remote entanglement generation are achieved through nuclear spin manipulation and telecommunications wavelength transitions. Understand the significance of these advances for quantum error correction, quantum networking, and distributed computing. Follow the experimental progress made with two ytterbium-171 systems at UIUC, including one featuring an optical cavity. Discover how this research contributes to understanding decoherence in many-body systems and measurement-induced phase transitions. Benefit from the expertise of Dr. Jacob Covey, whose previous work established record-breaking fidelity in Rydberg-based entanglement of individual alkaline earth atoms. Cover essential topics including quantum many-body entanglement, Rydberg blockade, atom-by-atom assembly, and nondestructive qubit readout in this comprehensive 58-minute presentation from Illinois Quantum.
