Resolving non-perturbative renormalization of a microwave-dressed weakly anharmonic superconducting qubit

Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Sercan Deve, Gary A. Steele, , | Summary: Microwave driving is a ubiquitous technique for superconducting qubits (SCQs), but the dressed states description based on the conventionally used perturbation theory cannot fully capture the dynamics in the strong driving limit. Comprehensive studies beyond these […]

Structured information extraction from complex scientific text with fine-tuned large language models

Kavli Affiliate: Kristin Persson | First 5 Authors: Alexander Dunn, John Dagdelen, Nicholas Walker, Sanghoon Lee, Andrew S. Rosen | Summary: Intelligently extracting and linking complex scientific information from unstructured text is a challenging endeavor particularly for those inexperienced with natural language processing. Here, we present a simple sequence-to-sequence approach to joint named entity recognition […]
