Optimal Decoding of Small Codes by Density Matrix Propagation
Anthony Benois, Pierre Cussenot, Grégoire Misguich +2
Accurate and efficient decoding is a crucial component for achieving fault-tolerant quantum computing. Realistic circuit-level noise introduces temporal correlations and degeneracy…
Qubits in second quantisation in fermionic simulators
Ahana Ghoshal, Carlos de Gois, Kiara Hansenne +2
Simulating many-body fermionic systems in conventional qubit-based quantum computers poses significant challenges due to the overheads associated with the encoding of fermionic sta…
No quantum advantage without classical communication: fundamental limitations of quantum networks
Justus Neumann, Tulja Varun Kondra, Kiara Hansenne +5
Quantum networks connect systems at separate locations via quantum links, enabling a wide range of quantum information tasks between distant parties. Large-scale networks have the…
Optimal Overlapping Tomography
Kiara Hansenne, Rui Qu, Lisa T. Weinbrenner +7
Characterising large-scale quantum systems is central to fundamental physics and essential for applications of quantum technologies. While a full characterisation requires exponent…
Certifying the Topology of Quantum Networks: Theory and Experiment
Lisa T. Weinbrenner, Nidhin Prasannan, Kiara Hansenne +5
Distributed quantum information in networks is paramount for global secure quantum communication. Moreover, it finds applications as a resource for relevant tasks, such as clock sy…
Covariance matrix-based criteria for network entanglement
Kiara Hansenne, Otfried Gühne
Quantum networks offer a realistic and practical scheme for generating multiparticle entanglement and implementing multiparticle quantum communication protocols. However, the corre…
Uncertainty relations from graph theory
Carlos de Gois, Kiara Hansenne, Otfried Gühne
Quantum measurements are inherently probabilistic and quantum theory often forbids to precisely predict the outcomes of simultaneous measurements. This phenomenon is captured and q…
Symmetries in quantum networks lead to no-go theorems for entanglement distribution and to verification techniques
Kiara Hansenne, Zhen-Peng Xu, Tristan Kraft +1
Quantum networks are promising tools for the implementation of long-range quantum communication. The characterization of quantum correlations in networks and their usefulness for i…
