Microwave Crosstalk in Planar Superconducting Quantum Devices
Yongxin Song, Dominic Hagmann, Kieran Dalton +5
Microwave crosstalk poses a major challenge to scaling superconducting quantum devices as it introduces excess control errors. Although its magnitude and impact have been explored…
Blind Quantum Computation on a Modular Superconducting Processor
Yongxin Song, Johannes Knörzer, Kieran Dalton +2
Current cloud-based quantum processors offer access to advanced hardware hosted on a remote server, but do not guarantee data or algorithm privacy. Blind quantum computation provid…
Resource-Efficient Cross-Platform Verification with Modular Superconducting Devices
Kieran Dalton, Johannes Knörzer, Finn Hoehne +7
Large-scale quantum computers are expected to benefit from modular architectures. Validating the capabilities of modular devices requires benchmarking strategies that assess perfor…
Performance Characterization of a Multi-Module Quantum Processor with Static Inter-Chip Couplers
Graham J. Norris, Kieran Dalton, Dante Colao Zanuz +8
Three-dimensional integration technologies such as flip-chip bonding are a key prerequisite to realize large-scale superconducting quantum processors. Modular architectures, in whi…
