Programmable Superradiance in an Interacting Qubit Array
Botao Du, Qihao Guo, Ruichao Ma
When multiple quantum emitters couple to a common electromagnetic environment, interference in their collective radiative dynamics gives rise to superradiance and subradiance. In r…
Entangling Superconducting Qubits via Energy-Selective Local Reservoirs
Qihao Guo, Botao Du, Ruichao Ma
Engineered dissipation provides a powerful route to controlling and stabilizing quantum states in open systems. Superconducting circuits are particularly suited to this approach du…
Towards a hybrid 3D transmon qubit with topological insulator-based Josephson junctions
Sheng-Wen Huang, Ramya Suresh, Jian Liao +5
Superconducting quantum circuits provide a versatile platform for studying quantum materials by leveraging precise microwave control and utilizing the tools of circuit quantum elec…
Tunneling Spectroscopy in Superconducting Circuit Lattices
Botao Du, Qihao Guo, Santiago López +1
We demonstrate tunneling spectroscopy of synthetic quantum matter in superconducting circuit lattices. We measure site-resolved excitation spectra by coupling the lattice to engine…
End-to-end workflow for machine learning-based qubit readout with QICK and hls4ml
Giuseppe Di Guglielmo, Botao Du, Javier Campos +10
We present an end-to-end workflow for superconducting qubit readout that embeds co-designed Neural Networks (NNs) into the Quantum Instrumentation Control Kit (QICK). Capitalizing…
