The persistent debate about the reality of a quantum state has recently come under limelight because of its importance to quantum information and the quantum computing community. Almost all of the deliberations are taking place using the elegant and powerful but abstract Hilbert space formalism of quantum mechanics developed with seminal contributions from John von Neumann. Since it is rather difficult to get a direct perception of the events in an abstract vector space, it is hard to trace the…

Quantum Information in Neural Systems
TLDR
The presented results show that fast decoherence timescales could assist cognitive binding through quantum entanglement across extensive neural networks in the brain cortex, and show that quantum coherence of individual subsystems cannot be used for cognitive binding because it is a physical mechanism that leads to separability and non-interaction.

Was Albert Einstein Wrong on Quantum Physics
Albert Einstein is considered by many physicists as the father of quantum physics in some sense. Yet there is an unshakable view that he was wrong on quantum physics. Although it may be a subject of

The physical interpretation of the quantum dynamics
The new quantum mechanics consists of a scheme of equations which are very closely analogous to the equations of classical mechanics, with the funda­mental difference that the dynamical variables do

THE paradox of Einstein, Podolsky and Rosen [1] was advanced as an argument that quantum mechanics could not be a complete theory but should be supplemented by additional variables. These additional

This paper proves that ontic indifference must be violated in any model reproducing quantum theory in which the quantum state is not a real thing.
Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?
TLDR
Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that one is led to conclude that the description of reality as given by a wave function is not complete.
The lightness of being: mass, ether, and unification of the forces
How can an electron be both a wave and a particle? At the same time? Because it is a quantum field. That key insight seems to be underappreciated, given the awe and mysticism that permeate most
Is a system's wave function in one-to-one correspondence with its elements of reality?
TLDR
It is shown, based only on the assumption that measurement settings can be chosen freely, that a system's wave function is in one-to-one correspondence with its elements of reality, which eliminates the possibility that it can be interpreted subjectively.

Credible reasons are presented to reveal that many of the lingering century old enigmas, surrounding the behavior of at least an individual quantum particle, can be comprehended in terms of an
Loophole-free Bell inequality violation using electron spins separated by 1.3 kilometres
TLDR
The data imply statistically significant rejection of the local-realist null hypothesis and could be used for testing less-conventional theories, and for implementing device-independent quantum-secure communication and randomness certification.
