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…
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…
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…
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…
Enhanced estimation of quantum properties with common randomized measurements
Benoît Vermersch, Aniket Rath, Bharathan Sundar +3
We present a technique for enhancing the estimation of quantum state properties by incorporating approximate prior knowledge about the quantum state of interest. This method involv…
Entanglement barrier and its symmetry resolution: theory and experiment
Aniket Rath, Vittorio Vitale, Sara Murciano +6
The operator entanglement (OE) is a key quantifier of the complexity of a reduced density matrix. In out-of-equilibrium situations, e.g. after a quantum quench of a product state,…
Quantum Fisher information from randomized measurements
Aniket Rath, Cyril Branciard, Anna Minguzzi +1
The quantum Fisher information (QFI) is a fundamental quantity of interest in many areas from quantum metrology to quantum information theory. It can in particular be used as a wit…
Importance sampling of randomized measurements for probing entanglement
Aniket Rath, Rick van Bijnen, Andreas Elben +2
We show that combining randomized measurement protocols with importance sampling allows for characterizing entanglement in significantly larger quantum systems and in a more effici…
