Double-Pumped Kerr Parametric Amplifier Beyond the Gain-Bandwidth Limit
Nicolas Zapata, Najmeh Etehadi Abari, Mitchell Field +5
Superconducting standingwave parametric amplifiers are crucial for the readout of microwave quantum devices. Despite significant improvements in recent years, the need to operat…
Low crosstalk modular flip-chip architecture for coupled superconducting qubits
Soeren Ihssen, Simon Geisert, Gabriel Jauma +10
We present a flip-chip architecture for an array of coupled superconducting qubits, in which circuit components reside inside individual microwave enclosures. In contrast to other…
Pure kinetic inductance coupling for cQED with flux qubits
Simon Geisert, Soeren Ihssen, Patrick Winkel +11
We demonstrate a qubit-readout architecture where the dispersive coupling is entirely mediated by a kinetic inductance. This allows us to engineer the dispersive shift of the reado…
Demonstrating a superconducting dual-rail cavity qubit with erasure-detected logical measurements
Kevin S. Chou, Tali Shemma, Heather McCarrick +31
A critical challenge in developing scalable error-corrected quantum systems is the accumulation of errors while performing operations and measurements. One promising approach is to…
Observation of Josephson Harmonics in Tunnel Junctions
Dennis Willsch, Dennis Rieger, Patrick Winkel +27
Approaches to developing large-scale superconducting quantum processors must cope with the numerous microscopic degrees of freedom that are ubiquitous in solid-state devices. State…
Dual-rail encoding with superconducting cavities
James D. Teoh, Patrick Winkel, Harshvardhan K. Babla +15
The design of quantum hardware that reduces and mitigates errors is essential for practical quantum error correction (QEC) and useful quantum computation. To this end, we introduce…
