Quantum theory is a well-defined local theory with a clear interpretation. No “measurement problem” or any other foundational matters are waiting to be settled.

An introduction to QBism with an application to the locality of quantum mechanics
We give an introduction to the QBist interpretation of quantum mechanics, which removes the paradoxes, conundra, and pseudo-problems that have plagued quantum foundations for the past nine decades.Expand

We study the S-matrix interpretation of quantum theory in light of Categotical Quantum Mechanics. The S-matrix interpretation of quantum theory is shown to be a functorial semantics relating theExpand
S-matrix interpretation in categorical quantum mechanics
We study the $S$-matrix interpretation of quantum theory in light of Categotical Quantum Mechanics. The $S$-matrix interpretation of quantum theory is shown to be a functorial semantics relating theExpand
On the Quantum Mechanical Measurement Process
The quantum mechanical measurement process is analyzed by means of an explicit generic model describing the interaction between object and measuring device. The solution of the Schrödinger equationExpand
On the Measurement Problem and the EPR Paradox
After a polarization measurement with photons in singlet state we know for certain the photons were in the measured state prior to measurement. Photons in singlet state do therefore not exhibitExpand

This is an elaboration of the “extra” advantage of the performance of quantized physical systems over classical ones, both in terms of single outcomes as well as probabilistic predictions. From aExpand
A Kolmogorov proof of the Clauser, Horne, Shimony and Holt inequalities
Boolean logic is used to prove the CHSH inequalities. The proof elucidates the connection be- tween Einstein elements of reality and quantum non locality. The violation of the CHSH inequality byExpand
Towards a Realistic Interpretation of Quantum Mechanics Providing a Model of the Physical World
TLDR
It is argued that a realistic interpretation of quantum physics is possible and useful and rests upon the assumption that quantum mechanics is a stochastic theory whose randomness derives from the existence of vacuum fields. Expand
Attempt at Perfecting Non-Relativistic Quantum Mechanics Based on Interaction
Many wave phenomena are related to interactions. Considering once neglected interactions in some cases, states of large objects and Newton's idea about measurement, we attempt to modify some conceptsExpand
Complementarity has empirically relevant consequences for the definition of quantum states.
TLDR
It is shown that the application of Bohr's main concepts of complementarity to the subsystems of a closed system requires a change in the definition of the quantum state, and such equivalence classes are necessary in order to maximize information entropy and achieve agreement with experimental entropy.

Purpose of this article is to stress the fact that Quantum Theory does not need an interpretation other than being an algorithm for computing probabilities associated with macroscopic phenomena andExpand
Weinberg's non-linear quantum mechanics and supraluminal communications
Abstract We show with an example that Weinberg's general framework for introducing non-linear corrections into quantum mechanics allows for arbitrarily fast communications.
Quantum nonlocality as an axiom
In the conventional approach to quantum mechanics, indeterminism is an axiom and nonlocality is a theorem. We consider inverting the logical order, making nonlocality an axiom and indeterminism aExpand
