Assessing the Sensitivity of Niobium- and Tantalum-Based Superconducting Qubits to Infrared Radiation
Michael Kerschbaum, Felix Wagner, Uroš Ognjanović +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…
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 (…
Realization of Constant-Depth Fan-Out with Real-Time Feedforward on a Superconducting Quantum Processor
Yongxin Song, Liberto Beltrán, Ilya Besedin +8
When using unitary gate sequences, the growth in depth of many quantum circuits with output size poses significant obstacles to practical quantum computation. The quantum fan-out o…
Enhancing Dispersive Readout of Superconducting Qubits Through Dynamic Control of the Dispersive Shift: Experiment and Theory
François Swiadek, Ross Shillito, Paul Magnard +9
The performance of a wide range of quantum computing algorithms and protocols depends critically on the fidelity and speed of the employed qubit readout. Examples include gate sequ…
Calibration of Drive Non-Linearity for Arbitrary-Angle Single-Qubit Gates Using Error Amplification
Stefania Lazăr, Quentin Ficheux, Johannes Herrmann +12
The ability to execute high-fidelity operations is crucial to scaling up quantum devices to large numbers of qubits. However, signal distortions originating from non-linear compone…
