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…
Quantum mechanics based on real numbers: A consistent description
Pedro Barrios Hita, Anton Trushechkin, Hermann Kampermann +2
Complex numbers play a crucial role in quantum mechanics. However, their necessity remains debated: whether they are fundamental or merely convenient. Recently, it was shown that a…
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…
Hybrid simplification rules for boundaries of quantum circuits
Michael Epping
We describe rules to simplify quantum circuits at their boundaries, i.e. at state preparation and measurement. There, any strictly incoherent operation may be pushed into a pre- or…
Withdrawn: A Measurement-based Algorithm for Graph Colouring
Michael Epping, Tobias Stollenwerk
In a previous version of this document we misinterpreted the runtime of a part of the described algorithm. Indeed, the runtime is not better than the Grover-Algorithm. We therefor…
Hamiltonians for one-way quantum repeaters
Filippo M. Miatto, Michael Epping, Norbert Lutkenhaus
Quantum information degrades over distance due to the unavoidable imperfections of the transmission channels, with loss as the leading factor. This simple fact hinders quantum comm…
