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…
Realizing a Continuous Set of Two-Qubit Gates Parameterized by an Idle Time
Colin Scarato, Kilian Hanke, Ants Remm +6
Continuous gate sets are a key ingredient for near-term quantum algorithms. Here, we demonstrate a hardware-efficient, continuous set of controlled arbitrary-phase ($\mathrm{C}Z_θ…
Calibrating Magnetic Flux Control in Superconducting Circuits by Compensating Distortions on Time Scales from Nanoseconds up to Tens of Microseconds
Christoph Hellings, Nathan Lacroix, Ants Remm +8
Fast tuning of the transition frequency of superconducting qubits using magnetic flux is essential, for example, for realizing high-fidelity two-qubit gates with low leakage or for…
Experimentally Informed Decoding of Stabilizer Codes Based on Syndrome Correlations
Ants Remm, Nathan Lacroix, Lukas Bödeker +9
High-fidelity decoding of quantum error correction codes relies on an accurate experimental model of the physical errors occurring in the device. Because error probabilities can de…
Realizing Lattice Surgery on Two Distance-Three Repetition Codes with Superconducting Qubits
Ilya Besedin, Michael Kerschbaum, Jonathan Knoll +12
Quantum error correction is needed for quantum computers to be capable of fault-tolerantly executing algorithms using hundreds of logical qubits. Recent experiments have demonstrat…
