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…
Quantum Graph States: Bridging Classical Theory and Quantum Innovation, Workshop Summary
Eric Chitambar, Kenneth Goodenough, Otfried Gühne +5
This workshop brought together experts in classical graph theory and quantum information science to explore the intersection of these fields, with a focus on quantum graph states a…
Two-point measurement correlations beyond the quantum regression theorem
Leonardo Santos, Otfried Gühne, Stefan Nimmrichter
Temporal correlations are fundamental in quantum physics, yet their computation is often challenging. The regression theorem (or hypothesis) serves as a key tool in this context, o…
Chiral Symmetries and Multiparticle Entanglement
Sophia Denker, Satoya Imai, Otfried Gühne
Bosons and fermions are defined by their exchange properties and the underlying symmetries determine the structure of the corresponding state spaces. For two particles there are tw…
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…
Ability of entanglement and purity to help to detect systematic experimental errors
Julia Freund, Francesco Basso Basset, Tobias M. Krieger +12
Measurements are central in all quantitative sciences, and a fundamental challenge is to make observations without systematic measurement errors. This holds in particular for quant…
