Multiplexed Readout of Superconducting Qubits Using a 3D Re-entrant Cavity Filter
Mustafa Bakr, Simone D. Fasciati, Shuxiang Cao +7
Hardware efficient methods for high fidelity quantum state measurements are crucial for superconducting qubit experiments, as qubit numbers grow and feedback and state reset begin…

Complementing the transmon by integrating a geometric shunt inductor
Simone D. Fasciati, Boris Shteynas, Giulio Campanaro +5
We realize a single-Josephson-junction transmon qubit shunted by a simple geometric inductor. We couple it capacitively to a conventional transmon and show that the ZZ interaction…

Efficient characterization of qudit logical gates with gate set tomography using an error-free Virtual-Z-gate model
Shuxiang Cao, Deep Lall, Mustafa Bakr +7
Gate-set tomography (GST) characterizes the process matrix of quantum logic gates, along with measurement and state preparation errors in quantum processors. GST typically requires…
