Abstract We reconstruct quantum theory starting from the premise that, as Asher Peres remarked, “Unperformed experiments have no results.” The tools of quantum information theory, and in particular the symmetric informationally complete (SIC) measurements, provide a concise expression of how exactly Peres’s dictum holds true. That expression is a constraint on how the probability distributions for outcomes of different, hypothetical and mutually exclusive experiments ought to mesh together, a… 
Letters for Andrei: QBism and the Unfinished Nature of Nature
Some time ago, Steven Weinberg wrote an article for the New York Review of Books with the title, “Symmetry: A ‘Key to Nature’s Secrets’.” So too, I would like to say of quantum information: Only by
Quantum Theory is a Quasi-stochastic Process Theory
There is a long history of representing a quantum state using a quasi-probability distribution: a distribution allowing negative values. In this paper we extend such representations to deal with
QBism: Quantum Theory as a Hero's Handbook
This paper represents an elaboration of the lectures delivered by one of us (CAF) during "Course 197 -- Foundations of Quantum Physics" at the International School of Physics "Enrico Fermi" in
Symmetric informationally complete measurements identify the irreducible difference between classical and quantum systems
We describe a general procedure for associating a minimal informationally-complete quantum measurement (or MIC) and a set of linearly independent post-measurement quantum states with a purely
Quantum Theory as Symmetry Broken by Vitality
I summarize a research program that aims to reconstruct quantum theory from a fundamental physical principle that, while a quantum system has no intrinsic hidden variables, it can be understood using
On Relationalist Reconstructions of Quantum Theory
One appealing feature of Carlo Rovelli’s proposal for “Relational Quantum Mechanics” [1] is that it offered a challenge for those who prefer technical work over slinging sentences: the reconstruction
Aims and Scope of the Special Issue, “Quantum Foundations: Informational Perspective”
During the past 30 years, the field of quantum information theory has produced a variety of novel information technologies whose full potential is as yet unknown. This quantum information revolution
Generalised qplexes, similarity to quantum state space, and 2-designs
We study the class of quantum measurements with the property that the image of the set of quantum states under the measurement map transforming states into probability distributions is similar to
Minimal informationally complete measurements for probability representation of quantum dynamics
In the present work, we suggest an approach for describing dynamics of finite-dimensional quantum systems in terms of pseudostochastic maps acting on probability distributions, which are obtained via
Discrete Wigner functions from informationally complete quantum measurements
Wigner functions provide a way to do quantum physics using quasiprobabilities, that is, "probability" distributions that can go negative. Informationally complete POVMs, a much younger subject than


Evidence for the epistemic view of quantum states: A toy theory
We present a toy theory that is based on a simple principle: the number of questions about the physical state of a system that are answered must always be equal to the number that are unanswered in a
QBism, the Perimeter of Quantum Bayesianism
This article summarizes the Quantum Bayesian point of view of quantum mechanics, with special emphasis on the view's outer edges---dubbed QBism. QBism has its roots in personalist Bayesian
Unknown Quantum States: The Quantum de Finetti Representation
We present an elementary proof of the quantum de Finetti representation theorem, a quantum analog of de Finetti’s classical theorem on exchangeable probability assignments. This contrasts with the
Quantum Mechanics as Quantum Information (and only a little more)
In this paper, I try once again to cause some good-natured trouble. The issue remains, when will we ever stop burdening the taxpayer with conferences devoted to the quantum foundations? The suspicion
Some Negative Remarks on Operational Approaches to Quantum Theory
This talk hopes to expand on points and convey some sense of why the author is fascinated with the problem of the symmetric informationally complete POVMs to an extent greater than axiomatic reconstructions.
This is a one-to-one translation of a German-written Ph.D. thesis from 1999. Quantum designs are sets of orthogonal projection matrices in finite(b)-dimensional Hilbert spaces. A fundamental
Properties of QBist State Spaces
Every quantum state can be represented as a probability distribution over the outcomes of an informationally complete measurement. But not all probability distributions correspond to quantum states.
Higher-order interference and single-system postulates characterizing quantum theory
We present a new characterization of quantum theory in terms of simple physical principles that is different from previous ones in two important respects: first, it only refers to properties of
Symmetric Informationally-Complete Quantum States as Analogues to Orthonormal Bases and Minimum-Uncertainty States
It is shown that if SIC-sets exist, they are as close to being an orthonormal basis for the space of density operators as possible and in prime dimensions, the standard construction for complete sets of mutually unbiased bases and Weyl-Heisenberg covariant Sic-sets are intimately related.
Relational quantum mechanics
I suggest that the common unease with taking quantum mechanics as a fundamental description of nature (the “measurement problem”) could derive from the use of an incorrect notion, as the unease with
