Two-qubit-gate operation in a high-connectivity transmon lattice utilizing a tunable coupling to a shared mode
Tuure Orell, Hao Hsu, Joona Andersson +3
Increasing connectivity and decreasing qubit-state delocalization without compromising the speed and accuracy of elementary gate operations are topical challenges in the developmen…
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…
Quantum error correction under numerically exact open-quantum-system dynamics
Aravind Plathanam Babu, Tuure Orell, Vasilii Vadimov +3
The known quantum error-correcting codes are typically built on approximative open-quantum-system models such as Born--Markov master equations. However, it is an open question how…
Collective bosonic effects in an array of transmon devices
Tuure Orell, Maximilian Zanner, Mathieu L. Juan +5
Multiple emitters coherently interacting with an electromagnetic mode give rise to collective effects such as correlated decay and coherent exchange interaction, depending on the s…
Coherent control of a symmetry-engineered multi-qubit dark state in waveguide quantum electrodynamics
Maximilian Zanner, Tuure Orell, Christian M. F. Schneider +5
Quantum information is typically encoded in the state of a qubit that is decoupled from the environment. In contrast, waveguide quantum electrodynamics studies qubits coupled to a…
Validity of Born-Markov master equations for single and two-qubit systems
Vasilii Vadimov, Jani Tuorila, Tuure Orell +4
The urgent need for reliable simulation tools to match the extreme accuracy needed to control tailored quantum devices highlights the importance of understanding open quantum syste…
Probing many-body localization phase transition with superconducting circuits
Tuure Orell, Alexios A. Michailidis, Maksym Serbyn +1
Chains of superconducting circuit devices provide a natural platform for studies of synthetic bosonic quantum matter. Motivated by the recent experimental progress in realizing dis…
