Microwave Quantum Link between Superconducting Circuits Housed in Spatially Separated Cryogenic Systems
Paul Magnard, Simon Storz, Philipp Kurpiers +10
Superconducting circuits are a strong contender for realizing quantum computing systems, and are also successfully used to study quantum optics and hybrid quantum systems. However,…
Realizing a Deterministic Source of Multipartite-Entangled Photonic Qubits
Jean-Claude Besse, Kevin Reuer, Michele C. Collodo +11
Sources of entangled electromagnetic radiation are a cornerstone in quantum information processing and offer unique opportunities for the study of quantum many-body physics in a co…
Benchmarking Coherent Errors in Controlled-Phase Gates due to Spectator Qubits
S. Krinner, S. Lazar, A. Remm +7
A major challenge in operating multi-qubit quantum processors is to mitigate multi-qubit coherent errors. For superconducting circuits, besides crosstalk originating from imperfect…
Improving the Performance of Deep Quantum Optimization Algorithms with Continuous Gate Sets
Nathan Lacroix, Christoph Hellings, Christian Kraglund Andersen +9
Variational quantum algorithms are believed to be promising for solving computationally hard problems and are often comprised of repeated layers of quantum gates. An example thereo…
Repeated Quantum Error Detection in a Surface Code
Christian Kraglund Andersen, Ants Remm, Stefania Lazar +6
The realization of quantum error correction is an essential ingredient for reaching the full potential of fault-tolerant universal quantum computation. Using a range of different s…
X-ray spectroscopy of current-induced spin-orbit torques and spin accumulation in Pt/3d transition metal bilayers
C. Stamm, C. Murer, Y. Acremann +10
An electric current flowing in Pt, a material with strong spin-orbit coupling, leads to spins accumulating at the interfaces by virtue of the spin Hall effect and interfacial charg…
