Gate-dependent offset charge shifts and anharmonicity in gatemon qubits in the weak tunneling regime
Utkan Güngördü, Rusko Ruskov, Silas Hoffman +3
Gatemon qubits are based on a superconductor-quantum dot-superconductor (S-QD-S) junction which enables in situ electrostatic tuning via a gate electrode. For a single-channel QD t…
Quantum dynamics of semiconductor quantum dot Josephson junctions
Utkan Güngördü, Rusko Ruskov, Silas Hoffman +3
Josephson junctions constructed from superconductor-semiconductor-superconductor heterostructures have been used to realize a variety of voltage-tunable superconducting quantum dev…
Demonstration of tunable three-body interactions between superconducting qubits
Tim Menke, William P. Banner, Thomas R. Bergamaschi +16
Nonpairwise multi-qubit interactions present a useful resource for quantum information processors. Their implementation would facilitate more efficient quantum simulations of molec…
Superconducting-semiconducting voltage-tunable qubits in the third dimension
Thomas M. Hazard, Andrew J. Kerman, Kyle Serniak +1
We propose superconducting-semiconducting (super-semi) qubit and coupler designs based on high-quality, compact through-silicon vias (TSVs). An interposer "probe" wafer containing…
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…
Demonstration of long-range correlations via susceptibility measurements in a one-dimensional superconducting Josephson spin chain
Daniel M. Tennant, Xi Dai, Antonio J. Martinez +20
Spin chains have long been considered an effective medium for long-range interactions, entanglement generation, and quantum state transfer. In this work, we explore the properties…
