Mean field theory of superglasses
Xiaoquan Yu, Markus Mueller
We study the interplay of superfluidity and glassy ordering of hard core bosons with random, frustrating interactions. This is motivated by bosonic systems such as amorphous supers…
Quantum measurement occurrence is undecidable
J. Eisert, M. P. Mueller, C. Gogolin
In this work, we show that very natural, apparently simple problems in quantum measurement theory can be undecidable even if their classical analogues are decidable. Undecidability…
Deriving quantum theory from its local structure and reversibility
Gonzalo de la Torre, Lluis Masanes, Anthony J. Short +1
We investigate the class of physical theories with the same local structure as quantum theory, but a potentially different global structure. It has previously been shown that any b…
The structure of reversible computation determines the self-duality of quantum theory
Markus P. Mueller, Cozmin Ududec
Predictions for measurement outcomes in physical theories are usually computed by combining two distinct notions: a state, describing the physical system, and an observable, descri…
Magnetoresistance and localization in bosonic insulators
Markus Mueller
We study the strong localization of hard core bosons. Using a locator expansion we find that in the insulator, unlike for typical fermion problems, nearly all low-energy scattering…
Unifying typical entanglement and coin tossing: on randomization in probabilistic theories
Markus P. Müller, Oscar C. O. Dahlsten, Vlatko Vedral
It is well-known that pure quantum states are typically almost maximally entangled, and thus have close to maximally mixed subsystems. We consider whether this is true for probabil…
