The parliament of observers - Against the observable axiom of quantum mechanics
Markus Frembs, Andreas Döring
The 'unreasonable effectiveness of mathematics in the natural sciences' may at times give the impression that natural science, especially modern theoretical physics, is all but a f…
A complete classification of the existence of finite-dimensional quantum solutions to inconsistent linear constraint systems
Markus Frembs
Linear constraint systems (LCS) provide a compact algebraic language for nonlocal games and state-independent contextuality. In the binary case the Mermin--Peres square shows that…
Contextuality in the -qubit Pauli group
Markus Frembs
The -qubit Pauli group is an essential ingredient to most quantum applications, from computing and error correction to benchmarking and simulation. Despite comprising merely a d…
Unextendible stabiliser bases
Markus Frembs
We study incomplete sets of orthogonal stabiliser states that cannot be extended by a further stabiliser state orthogonal to all of its members. Such sets are the stabiliser analog…
Maximal complementarity in the n-qubit Pauli group
Markus Frembs, Giovanni Natale, Christopher S. P. Wever +1
Observables in quantum mechanics are generally complementary, that is, they reveal mutually incompatible pieces of information about a given system. This property is not only a fun…
An algebraically closed family of informational n-qubit purity invariants
Markus Frembs, Giovanni Natale, Christopher S. P. Wever +1
We present a family of quadratics in Pauli expectation values, and prove that they constitute state-independent invariants for all n-qubit pure states. This family generalises the…
No quantum solutions to linear constraint systems from monomial measurement-based quantum computation in odd prime dimension
Markus Frembs, Cihan Okay, Ho Yiu Chung
We combine the study of resources in measurement-based quantum computation (MBQC) with that of quantum solutions to linear constraint systems (LCS). Contextuality of the input stat…
