Distinguishing multi-spin interactions from lower-order effects
Thomas R. Bergamaschi, Tim Menke, William P. Banner +5
Multi-spin interactions can be engineered with artificial quantum spins. However, it is challenging to verify such interactions experimentally. Here we describe two methods to char…
Mediated interactions beyond the nearest neighbor in an array of superconducting qubits
Yariv Yanay, Jochen Braumüller, Terry P. Orlando +3
We consider mediated interactions in an array of floating transmons, where each qubit capacitor consists of two superconducting pads galvanically isolated from ground. Each such pa…
Quantum transport and localization in 1d and 2d tight-binding lattices
Amir H. Karamlou, Jochen Braumüller, Yariv Yanay +16
Particle transport and localization phenomena in condensed-matter systems can be modeled using a tight-binding lattice Hamiltonian. The ideal experimental emulation of such a model…
CircuitQ: An open-source toolbox for superconducting circuits
Philipp Aumann, Tim Menke, William D. Oliver +1
We introduce CircuitQ, an open-source toolbox for the analysis of superconducting circuits implemented in Python. It features the automated construction of a symbolic Hamiltonian o…
Improving qubit coherence using closed-loop feedback
Antti Vepsäläinen, Roni Winik, Amir H. Karamlou +11
Superconducting qubits are a promising platform for building a larger-scale quantum processor capable of solving otherwise intractable problems. In order for the processor to reach…
Lindblad Tomography of a Superconducting Quantum Processor
Gabriel O. Samach, Ami Greene, Johannes Borregaard +15
As progress is made towards the first generation of error-corrected quantum computers, robust characterization and validation protocols are required to assess the noise environment…
Fabrication of superconducting through-silicon vias
Justin L. Mallek, Donna-Ruth W. Yost, Danna Rosenberg +15
Increasing circuit complexity within quantum systems based on superconducting qubits necessitates high connectivity while retaining qubit coherence. Classical micro-electronic syst…
Error mitigation via stabilizer measurement emulation
A. Greene, M. Kjaergaard, M. E. Schwartz +16
Dynamical decoupling (DD) is a widely-used quantum control technique that takes advantage of temporal symmetries in order to partially suppress quantum errors without the need reso…
Deep Neural Network Discrimination of Multiplexed Superconducting Qubit States
Benjamin Lienhard, Antti Vepsäläinen, Luke C. G. Govia +15
Demonstrating a quantum computational advantage will require high-fidelity control and readout of multi-qubit systems. As system size increases, multiplexed qubit readout becomes a…
Probing quantum information propagation with out-of-time-ordered correlators
Jochen Braumüller, Amir H. Karamlou, Yariv Yanay +13
Interacting many-body quantum systems show a rich array of physical phenomena and dynamical properties, but are notoriously difficult to study: they are challenging analytically an…
