Unobservables and Decoherence from Complexity
Michael Epping, Jochen Szangolies
The interface between the quantum and the classical is an intriguing and, at times, hotly contested subject of ongoing research. The quantum regime is characterized by interference…
The Standard Model Symmetry and Qubit Entanglement
Jochen Szangolies
Research at the intersection of quantum gravity and quantum information theory has seen significant success in describing the emergence of spacetime and gravity from quantum states…
Noise-Robust Detection of Quantum Phase Transitions
Kevin Lively, Tim Bode, Jochen Szangolies +2
Quantum computing allows for the manipulation of highly correlated states whose properties quickly go beyond the capacity of any classical method to calculate. Thus one natural pro…
Calibration of syndrome measurements in a single experiment
Christian Wimmer, Jochen Szangolies, Michael Epping
Quantum error correction can reduce the effects of noise in quantum systems, e.g. in metrology or most notably in quantum computing. Typically, this requires making measurements th…
The Quantum Rashomon Effect: A Strengthened Frauchiger-Renner Argument
Jochen Szangolies
The Frauchiger-Renner argument aims to show that `quantum theory cannot consistently describe the use of itself': in many-party settings where agents are themselves subject to quan…
Epistemic Horizons: This Sentence is
Jochen Szangolies
In [Found. Phys. 48.12 (2018): 1669], the notion of 'epistemic horizon' was introduced as an explanation for many of the puzzling features of quantum mechanics. There, it was shown…
Epistemic Horizons and the Foundations of Quantum Mechanics
Jochen Szangolies
In-principle restrictions on the amount of information that can be gathered about a system have been proposed as a foundational principle in several recent reconstructions of the f…
Device-Independent Bounds on Detection Efficiency
Jochen Szangolies, Hermann Kampermann, Dagmar Bruß
In many quantum information applications, a minimum detection efficiency must be exceeded to ensure success. Protocols depending on the violation of a Bell inequality, for instance…
Detecting Entanglement of Unknown Quantum States with Random Measurements
Jochen Szangolies, Hermann Kampermann, Dagmar Bruß
In quantum information theory, the reliable and effective detection of entanglement is of paramount importance. However, given an unknown state, assessing its entanglement is a cha…
Tests against noncontextual models with measurement disturbances
Jochen Szangolies, Matthias Kleinmann, Otfried Gühne
The testability of the Kochen-Specker theorem is a subject of ongoing controversy. A central issue is that experimental implementations relying on sequential measurements cannot ac…
