Towards a Realistic Interpretation of Quantum Mechanics Providing a Model of the Physical World

- Physics, Computer Science
- 2012

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

- Physics
- 2013

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 concepts… Expand

Complementarity has empirically relevant consequences for the definition of quantum states.

- Computer Science, Physics
- 2019

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.

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 a… Expand
