Hybrid Quantum-Classical Neural Networks for Recognizing Quantum Phases
Colin Scarato, Johannes Knörzer, Markus K. Hoffmann +11
Identifying quantum phases of matter is key to understanding strongly correlated materials, but remains a challenging task for both conventional computers and current quantum proce…
Lattice surgery for near-term experimental logical qubit entanglement creation in planar architectures
Lukas Bödeker, Ãron Márton, Luis Colmenarez +3
In the era of early fault-tolerant quantum computing, basic demonstrations of entanglement operations between a few logical qubits are at the frontier of recent developments in qua…
Frequency-resolved decoherence spectroscopy of a semiconductor charge qubit coupled to a high-impedance resonator
Ekaterina Al-Tavil, Wonjin Jang, David J. van Woerkom +10
Superconducting resonators coupled to semiconductor quantum dots provide a powerful platform to investigate light-matter interaction and decoherence mechanisms in solid-state quant…
Microwave Crosstalk in Planar Superconducting Quantum Devices
Yongxin Song, Dominic Hagmann, Kieran Dalton +5
Microwave crosstalk poses a major challenge to scaling superconducting quantum devices as it introduces excess control errors. Although its magnitude and impact have been explored…
Blind Quantum Computation on a Modular Superconducting Processor
Yongxin Song, Johannes Knörzer, Kieran Dalton +2
Current cloud-based quantum processors offer access to advanced hardware hosted on a remote server, but do not guarantee data or algorithm privacy. Blind quantum computation provid…
A Modular Cryogenic Link for Microwave Quantum Communication Over Distances of Tens of Meters
Josua D. Schär, Simon Storz, Paul Magnard +6
Quantum technologies promise a radically new way to solve classically intractable computing problems. Superconducting circuits as a platform are at the forefront of this field. The…
