Experimental study of modified Tavis-Cummings model with directly-coupled superconducting artificial atoms

2023 · Optics Express

The Tavis-Cummings model is intensively investigated in quantum optics and has important applications in generation of multi-atom entanglement. Here, we employ a superconducting circuit quantum electrodynamic system to study a modified Tavis-Cummings model with directly-coupled …

Systematic Characterization of Transmon Qubit Stability with Thermal Cycling

2026 · Entropy

The temporal stability and reproducibility of qubit parameters are critical for the long-term operation and maintenance of superconducting quantum processors. In this work, we present a comprehensive longitudinal characterization of 27 frequency-tunable transmon qubits spanning …
