Learning Lindblad Dynamics of a Superconducting Quantum Processor
Johann Bock Severin, Malthe A. Marciniak, Rune Thinggaard Birke +13
Accurate models of quantum processors are essential for understanding, calibrating, and improving their performance. In practice, model construction must balance physical detail ag…
Junction-Intrinsic Dissipation in Hybrid Superconductor-Semiconductor Gatemon Qubits
Zhenhai Sun, David Feldstein-Bofill, Ksenia Shagalov +10
Superconducting transmon qubits based on hybrid superconductor-semiconductor Josephson junctions (gatemons) offer gate tunability, but their relaxation times remain well below thos…
Demonstrating and Benchmarking Classical Shadows for Lindblad Tomography
Rune Thinggaard Birke, Johann Bock Severin, Malthe A. Marciniak +15
Spurious couplings and decoherence degrade the performance of solid-state quantum processors, demanding careful design, calibration, and mitigation protocols. These strategies ofte…
Millisecond-Scale Calibration and Benchmarking of Superconducting Qubits
Malthe A. Marciniak, Rune T. Birke, Johann B. Severin +13
Superconducting qubit parameters drift on sub-second timescales, motivating calibration and benchmarking techniques that can be executed on millisecond timescales. We demonstrate a…
Controlled Parity of Cooper Pair Tunneling in a Hybrid Superconducting Qubit
David Feldstein-Bofill, Leo Uhre Jakobsen, Ksenia Shagalov +9
Superconducting quantum circuits derive their nonlinearity from the Josephson energy-phase relation. Besides the fundamental term, this relation can also contain higher Fou…
