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…
A Modular Cryogenic Link for Microwave Quantum Communication Over Distances of Tens of Meters
Josua D. Schär, Simon Storz, Paul Magnard +6
Quantum technologies promise a radically new way to solve classically intractable computing problems. Superconducting circuits as a platform are at the forefront of this field. The…
Emission and Absorption of Microwave Photons in Orthogonal Temporal Modes across a 30-Meter Two-Node Network
Alonso Hernández-Antón, Josua D. Schär, Aleksandr Grigorev +6
The tunable interaction between stationary quantum bits and propagating modes of light allows for the encoding of quantum information in the state of itinerant photons. This abilit…
Assessing the Sensitivity of Niobium- and Tantalum-Based Superconducting Qubits to Infrared Radiation
Michael Kerschbaum, Felix Wagner, UroÅ¡ OgnjanoviÄ +7
The use of tantalum films for superconducting qubits has recently extended qubit coherence times significantly, primarily due to reduced dielectric losses at the metal-air interfac…
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…
