Emergent universality in Kraus maps of quantum chaotic many-body dynamics

Qi Camm Huang, Wai-Keong Mok, Tobias Haug +1

Recent studies of "deep thermalization" have revealed universal physics in quantum many-body dynamics beyond equilibration towards Gibbs states: maximally random quantum state ense…

Universal equilibrium magic in quantum many-body systems

Soumyadeep Sarma, Tobias Haug, John Preskill +1

Thermalization conventionally describes local properties of isolated many-body systems at equilibrium. Magic, or nonstabilizerness $\unicode{x2013}$ the resource enabling universal…

Practical Tests and Witnesses of Fermionic non-Gaussianity

Tobias Haug, Xhek Turkeshi, Piotr Sierant

Fermionic Gaussian states describe free fermions and underlie the mean-field picture of matter, from metals to superconductors; they are also efficiently simulable on classical com…

Nature is stingy: Universality of Scrooge ensembles in quantum many-body systems

Wai-Keong Mok, Tobias Haug, Wen Wei Ho +1

Recent advances in quantum simulators allow direct experimental access to ensembles of pure states generated by measuring part of an isolated quantum many-body system. These projec…

Triangle Criterion: a mixed-state magic criterion with applications in distillation and detection

Zhenhuan Liu, Tobias Haug, Qi Ye +2

We introduce a mixed-state magic criterion, the Triangle Criterion, which plays a role for magic analogous to the Positive Partial Transposition (PPT) Criterion for entanglement: i…

A scalable advantage in multi-photon quantum machine learning

Yong Wang, Zhenghao Yin, Tobias Haug +6

Photons are promising candidates for quantum information technology due to their high robustness and long coherence time at room temperature. Inspired by the prosperous development…

Quantifying mixed-state entanglement via partial transpose and realignment moments

Poetri Sonya Tarabunga, Tobias Haug

Entanglement plays a crucial role in quantum information science and many-body physics, yet quantifying it in mixed quantum many-body systems has remained a notoriously difficult p…

Efficient witnessing and testing of magic in mixed quantum states

Tobias Haug, Poetri Sonya Tarabunga

Nonstabilizerness or `magic' is a crucial resource for quantum computers which can be distilled from noisy quantum states. However, determining the magic of mixed quantum has been…

Efficient mutual magic and magic capacity with matrix product states

Poetri Sonya Tarabunga, Tobias Haug

Stabilizer Rényi entropies (SREs) probe the non-stabilizerness (or magic) of many-body systems and quantum computers. Here, we introduce the mutual von-Neumann SRE and magic capaci…

A nonstabilizerness monotone from stabilizerness asymmetry

Poetri Sonya Tarabunga, Martina Frau, Tobias Haug +2

We introduce a nonstabilizerness monotone which we name basis-minimised stabilizerness asymmetry (BMSA). It is based on the notion of -asymmetry, a measure of how much a certain…
