Scqubits: a Python package for superconducting qubits
Peter Groszkowski, Jens Koch
is an open-source Python package for simulating and analyzing superconducting circuits. It provides convenient routines to obtain energy spectra of common super…
Moving beyond the transmon: Noise-protected superconducting quantum circuits
András Gyenis, Agustin Di Paolo, Jens Koch +3
Artificial atoms realized by superconducting circuits offer unique opportunities to store and process quantum information with high fidelity. Among them, implementations of circuit…
Variational tight-binding method for simulating large superconducting circuits
D. K. Weiss, Wade DeGottardi, Jens Koch +1
We generalize solid-state tight-binding techniques for the spectral analysis of large superconducting circuits. We find that tight-binding states can be better suited for approxima…
Robust Quantum Optimal Control with Trajectory Optimization
Thomas Propson, Brian E. Jackson, Jens Koch +2
The ability to engineer high-fidelity gates on quantum processors in the presence of systematic errors remains the primary barrier to achieving quantum advantage. Quantum optimal c…
