Equivalence of contextuality and Wigner function negativity in continuous-variable quantum optics
Jonas Haferkamp, Juani Bermejo-Vega
One of the central foundational questions of physics is to identify what makes a system quantum as opposed to classical. One seminal notion of classicality of a quantum system is t…
Learnability of the output distributions of local quantum circuits
Marcel Hinsche, Marios Ioannou, Alexander Nietner +6
There is currently a large interest in understanding the potential advantages quantum devices can offer for probabilistic modelling. In this work we investigate, within two differe…
Resource theory of quantum uncomplexity
Nicole Yunger Halpern, Naga B. T. Kothakonda, Jonas Haferkamp +3
Quantum complexity is emerging as a key property of many-body systems, including black holes, topological materials, and early quantum computers. A state's complexity quantifies th…
Linear growth of quantum circuit complexity
Jonas Haferkamp, Philippe Faist, Naga B. T. Kothakonda +2
Quantifying quantum states' complexity is a key problem in various subfields of science, from quantum computing to black-hole physics. We prove a prominent conjecture by Brown and…
Emergent statistical mechanics from properties of disordered random matrix product states
Jonas Haferkamp, Christian Bertoni, Ingo Roth +1
The study of generic properties of quantum states has led to an abundance of insightful results. A meaningful set of states that can be efficiently prepared in experiments are grou…
