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…
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…
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…
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…
