A Versatile Analytical Model for Fast and Accurate Determination of Feedline-Coupled Resonators for Superconducting Qubit Readout
Zhen Luo, Lea Richard, Ivan Tsitsilin +4
Superconducting quantum chips commonly utilize quarter-wavelength (λ/4) transmission line resonators as readout circuits. An analytical model for the accurate determination of res…
Scalable Single-Step Generation of W States in 2D Superconducting Qubit Lattices
João H. Romeiro, Federico A. Roy, Niklas Bruckmoser +13
The reliable generation of multi-qubit entanglement is a prerequisite for large-scale quantum information technologies. In particular, W states are a valuable resource owing to the…
Non-Markovian thermal reservoirs for autonomous entanglement distribution
Joan AgustÃ, Christian M. F. Schneider, Kirill G. Fedorov +2
We describe a novel scheme for the generation of stationary entanglement between two separated qubits that are driven by a purely thermal photon source. While in this scenario the…
Theory of Multi-photon Processes for Applications in Quantum Control
Longxiang Huang, Jacquelin Luneau, Johannes Schirk +5
We present a general theoretical framework for evaluating multi-photon processes in periodically driven quantum systems, which have been identified as a versatile tool for engineer…
Enhancing Variational Quantum Eigensolvers for SU(2) Lattice Gauge Theory via Systematic State Preparation
Klaus Liegener, Dominik Mattern, Alexander Korobov +7
Computing the vacuum and energy spectrum in non-Abelian, interacting lattice gauge theories remains an open challenge, in part because approximating the continuum limit requires la…
Experimental setup for the combined study of spin ensembles and superconducting quantum circuits
Lukas Vogl, Gerhard B. P. Huber, Ana StriniÄ +5
A hybrid quantum computing architecture combining quantum processors and quantum memory units allows for exploiting each component's unique properties to enhance the overall perfor…
