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…
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…
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…
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…
