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…
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…
Reducing leakage of single-qubit gates for superconducting quantum processors using analytical control pulse envelopes
Eric Hyyppä, Antti Vepsäläinen, Miha PapiÄ +10
Improving the speed and fidelity of quantum logic gates is essential to reach quantum advantage with future quantum computers. However, fast logic gates lead to increased leakage e…
Zeptojoule Calorimetry
András Gunyhó, Kassius Kohvakka, Qi-Ming Chen +4
The measurement of energy is a fundamental tool used, for example, in exploring the early universe, characterizing particle decay processes, as well as in quantum technology and co…
