Investigation of microwave loss induced by oxide regrowth in high-Q Nb resonators
J. Verjauw, A. Potočnik, M. Mongillo +16
The coherence of state-of-the-art superconducting qubit devices is predominantly limited by two-level-system defects, found primarily at amorphous interface layers. Reducing microw…
Millikelvin temperature cryo-CMOS multiplexer for scalable quantum device characterisation
Anton Potočnik, Steven Brebels, Jeroen Verjauw +11
Quantum computers based on solid state qubits have been a subject of rapid development in recent years. In current Noisy Intermediate-Scale Quantum (NISQ) technology, each quantum…
Observation of the Crossover from Photon Ordering to Delocalization in Tunably Coupled Resonators
Michele C. Collodo, Anton Potočnik, Simone Gasparinetti +6
Networks of nonlinear resonators offer intriguing perspectives as quantum simulators for non-equilibrium many-body phases of driven-dissipative systems. Here, we employ photon corr…
Rapid high-fidelity multiplexed readout of superconducting qubits
Johannes Heinsoo, Christian Kraglund Andersen, Ants Remm +8
The duration and fidelity of qubit readout is a critical factor for applications in quantum information processing as it limits the fidelity of algorithms which reuse qubits after…
Realization of a quantum random generator certified with the Kochen-Specker theorem
Anatoly Kulikov, Markus Jerger, Anton Potočnik +2
Random numbers are required for a variety of applications from secure communications to Monte-Carlo simulation. Yet randomness is an asymptotic property and no output string genera…
Realizing Rapid, High-Fidelity, Single-Shot Dispersive Readout of Superconducting Qubits
T. Walter, P. Kurpiers, S. Gasparinetti +8
The speed of quantum gates and measurements is a decisive factor for the overall fidelity of quantum protocols when performed on physical qubits with finite coherence time. Reducin…
Superconducting Quantum Simulator for Topological Order and the Toric Code
Mahdi Sameti, Anton Potocnik, Dan E. Browne +2
Topological order is now being established as a central criterion for characterizing and classifying ground states of condensed matter systems and complements categorizations based…
Contextuality without nonlocality in a superconducting quantum system
Markus Jerger, Yarema Reshitnyk, Markus Oppliger +8
Classical realism demands that system properties exist independently of whether they are measured, while noncontextuality demands that the results of measurements do not depend on…
Magnetic order and low-energy excitations in the quasi-one-dimensional antiferromagnet CuSeO with staggered fields
M. Herak, A. Zorko, M. Pregelj +9
Ground state and low-energy excitations of the quasi-one-dimensional antiferromagnet CuSeO were experimentally studied using bulk magnetization, neutron diffraction, muon s…
Orthorhombic fulleride (CH3NH2)K3C60 close to Mott-Hubbard instability: Ab initio study
Anton Potočnik, Nicola Manini, Matej Komelj +2
We study the electronic structure and magnetic interactions in methylamine-intercalated orthorhombic alkali-doped fullerene (CH3NH2)K3C60 within the density functional theory. As i…
Symmetric and antisymmetric exchange anisotropies in quasi-one-dimensional CuSeO as revealed by ESR
M. Herak, A. Zorko, D. Arcon +5
We present an electron spin resonance (ESR) study of single-crystalline spin chain-system CuSeO in the frequency range between 9 GHz and 450 GHz. In a wide temperature rang…
