Mitigating crosstalk errors for simultaneous single-qubit gates on a superconducting quantum processor
Jaap J. Wesdorp, Eric Hyyppä, Joona Andersson +61
Single-qubit gates on superconducting quantum processors are typically implemented using microwave pulses applied through dedicated control lines. However, these microwave pulses m…
Above 99.9% Fidelity Single-Qubit Gates, Two-Qubit Gates, and Readout in a Single Superconducting Quantum Device
Fabian Marxer, Jakub Mrożek, Joona Andersson +64
Achieving high-fidelity single-qubit gates, two-qubit gates, and qubit readout is critical for building scalable, error-corrected quantum computers. However, device parameters that…
A Superconducting Qubit-Resonator Quantum Processor with Effective All-to-All Connectivity
Michael Renger, Jeroen Verjauw, Nicola Wurz +62
In this work we introduce a superconducting quantum processor architecture that uses a transmission-line resonator to implement effective all-to-all connectivity between six transm…
Technology and Performance Benchmarks of IQM's 20-Qubit Quantum Computer
Leonid Abdurakhimov, Janos Adam, Hasnain Ahmad +111
Quantum computing has tremendous potential to overcome some of the fundamental limitations present in classical information processing. Yet, today's technological limitations in th…
Software tools for quantum control: Improving quantum computer performance through noise and error suppression
Harrison Ball, Michael J. Biercuk, Andre Carvalho +10
Manipulating quantum computing hardware in the presence of imperfect devices and control systems is a central challenge in realizing useful quantum computers. Susceptibility to noi…
Quantum--Classical Interface Based on Single Flux Quantum Digital Logic
R. McDermott, M. G. Vavilov, B. L. T. Plourde +4
We describe an approach to the integrated control and measurement of a large-scale superconducting multiqubit circuit using a proximal coprocessor based on the Single Flux Quantum…
Implementation of the iFREDKIN gate in scalable superconducting architecture for the quantum simulation of Fermionic systems
Per J. Liebermann, Pierre-Luc Dallaire-Demers, Frank K. Wilhelm
We present a Superconducting Planar ARchitecture for Quantum Simulations (SPARQS) intended to implement a scalable qubit layout for quantum simulators. To this end, we describe the…
Optimized cross-resonance gate for coupled transmon systems
Susanna Kirchhoff, Torsten Keßler, Per J. Liebermann +4
The cross-resonant gate is an entangling gate for fixed frequency superconducting qubits introduced for untunable qubits. While being simple and extensible, it suffers from long du…
Optimal Qubit Control Using Single-Flux Quantum Pulses
Per J. Liebermann, Frank K. Wilhelm
Single flux quantum pulses are a natural candidate for on-chip control of superconducting qubits. We show that they can drive high-fidelity single-qubit rotations---even in leaky t…
