Biorthogonal quantum mechanics

DC Brody - Journal of Physics A: Mathematical and Theoretical, 2013‏ - iopscience.iop.org
The Hermiticity condition in quantum mechanics required for the characterization of (a)
physical observables and (b) generators of unitary motions can be relaxed into a wider class …

Quantum correlations with no causal order

O Oreshkov, F Costa, Č Brukner - Nature communications, 2012‏ - nature.com
The idea that events obey a definite causal order is deeply rooted in our understanding of
the world and at the basis of the very notion of time. But where does causal order come from …

On the quantum measurement problem

Č Brukner - Quantum [un] speakables II: half a century of Bell's …, 2017‏ - Springer
In this paper, I attempt a personal account of my understanding of the measurement problem
in quantum mechanics, which has been largely in the tradition of the Copenhagen …

Quantum theory and beyond: Is entanglement special?

B Dakic, C Brukner - arxiv preprint arxiv:0911.0695, 2009‏ - arxiv.org
Quantum theory makes the most accurate empirical predictions and yet it lacks simple,
comprehensible physical principles from which the theory can be uniquely derived. A broad …

Probabilistic theories and reconstructions of quantum theory

M Müller - SciPost Physics Lecture Notes, 2021‏ - scipost.org
These lecture notes provide a basic introduction to the framework of generalized
probabilistic theories (GPTs) and a sketch of a reconstruction of quantum theory (QT) from …

Information invariance and quantum probabilities

Č Brukner, A Zeilinger - Foundations of Physics, 2009‏ - Springer
We consider probabilistic theories in which the most elementary system, a two-dimensional
system, contains one bit of information. The bit is assumed to be contained in any complete …

[HTML][HTML] Toolbox for reconstructing quantum theory from rules on information acquisition

PA Höhn - Quantum, 2017‏ - quantum-journal.org
We develop an operational approach for reconstructing the quantum theory of qubit systems
from elementary rules on information acquisition. The focus lies on an observer $ O …

Quantum superposition of thermodynamic evolutions with opposing time's arrows

G Rubino, G Manzano, Č Brukner - Communications Physics, 2021‏ - nature.com
Microscopic physical laws are time-symmetric, hence, a priori there exists no preferential
temporal direction. However, the second law of thermodynamics allows one to associate the …

[ספר][B] Quantum Computing in the Arts and Humanities

ER Miranda - 2022‏ - Springer
Publications reporting research into quantum information processing started to emerge
around the middle of the 1970s; eg Holevo (1973), Poplavskii (1975) and Ingarden (1976) …

No preferred reference frame at the foundation of quantum mechanics

W Stuckey, T McDevitt, M Silberstein - Entropy, 2021‏ - mdpi.com
Quantum information theorists have created axiomatic reconstructions of quantum
mechanics (QM) that are very successful at identifying precisely what distinguishes quantum …
