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…
Quantum error detection in qubit-resonator star architecture
Florian Vigneau, Sourav Majumder, Aniket Rath +13
Achieving industrial quantum advantage is unlikely without the use of quantum error correction (QEC). Other QEC codes beyond surface code are being experimentally studied, such as…
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…
Observing the quantum Mpemba effect in quantum simulations
Lata Kh Joshi, Johannes Franke, Aniket Rath +9
The non-equilibrium physics of many-body quantum systems harbors various unconventional phenomena. In this study, we experimentally investigate one of the most puzzling of these ph…
Robust estimation of the Quantum Fisher Information on a quantum processor
Vittorio Vitale, Aniket Rath, Petar Jurcevic +3
We present the experimental measurement, on a quantum processor, of a series of polynomial lower bounds that converge to the quantum Fisher information (QFI), a fundamental quantit…
Thermalization and Criticality on an Analog-Digital Quantum Simulator
Trond I. Andersen, Nikita Astrakhantsev, Amir H. Karamlou +224
Understanding how interacting particles approach thermal equilibrium is a major challenge of quantum simulators. Unlocking the full potential of such systems toward this goal requi…
