Entanglement and Quantum non-locality: an experimental perspective
The theory of Quantum Mechanics is one of the mainstay of modern physics, a well-established mathematical clockwork whose strength and accuracy in predictions are currently experienced in worldwide…
Experimental tests of hidden variable theories from dBB to stochastic electrodynamics
The studies concerning the possible existence of a deterministic theory, of which quantum mechanics would be an approximation, date to the celebrated 1935 Einstein-Podolsky-Rosen paper. Since Bell's…
SUPERQUANTUM CORRELATIONS IN NON-LOCAL HIDDEN VARIABLE THEORIES
Quantum mechanical phenomena have a ected our lives in numerous ways. Their impact on modern technology ranges from everyday applications such as transistors, lasers and solar cells to ground…
Origin of Quantum Mechanical Results and Life: A Clue from Quantum Biology
Although quantum mechanics can accurately predict the probability distribution of outcomes in an ensemble of identical systems, it cannot predict the result of an individual system. All the local and…
Unexpected reemergence of the von Neumann theorem
Is is shown here that the "simple test of quantumness for a single system" of arXiv:0704.1962 (for a recent experimental realization see arXiv:0804.1646) has exactly the same relation to the…
No return to classical reality
This article reviews results on the fundamental phenomena of quantum theory that cannot be understood in classical terms and describes some aspects of quantum physics that can never admit a classical understanding – the intrinsically quantum mechanical aspects of nature.
Quantum Mechanics Needs Interpretation
Since the beginning, quantum mechanics has raised major foundational and interpretative problems. Foundational research has been an important factor in the development of quantum cryptography,…
Embedding Quantum Mechanics into a Broader Noncontextual Theory
A new informal presentation of the extended semantic realism (ESR) model is supplied which embodies the formalism of QM into a broader mathematical formalism and reinterprets quantum probabilities as conditional on detection rather than absolute and justifies the assumptions introduced in the ESR model and proves its objectivity.
Entanglement: Quantum or Classical?
- Physics, PhilosophyReports on progress in physics. Physical Society
This work discusses some inequalities and bounds that are violated by quantum states thereby falsifying the existence of some of the classical hidden variables theories and discusses some exciting manifestations of entanglement, such as N00N states and the non-separable single particle states.

Experimental realization of a first test of de Broglie-Bohm theory
Quantum mechanics is a pillar of modern physics, confirmed by a huge number of experiments. Nevertheless, it presents many unintuitive properties, strongly differing from classical mechanics due to…
Quantum gravity as a dissipative deterministic system
It is argued that the so-called holographic principle will obstruct attempts to produce physically realistic models for the unification of general relativity with quantum mechanics, unless…
The statistical interpretation of quantum mechanics
The Statistical Interpretation of quantum theory is formulated for the purpose of providing a sound interpretation using a minimum of assumptions. Several arguments are advanced in favor of…
A Proposed Solution of the Measurement Problem in Quantum Mechanics by a Hidden Variable Theory
The measurement problem in quantum mechanics is re-examined and it is shown that it cannot really be solved in a satisfactory way, within the framework of the usual interpretation of the theory. We…
Critical analysis of the empirical tests of local hidden-variable theories.
- PhysicsPhysical review. A, Atomic, molecular, and optical physics
It is proved that homogeneous inequalities, involving only coincidence detection rates, cannot discriminate between quantum mechanics and local theories, which invalidates all previously used empirical tests and conjectured that quantum mechanics might be compatible with local realism.
Locality and causality in hidden-variables models of quantum theory
Motivated by Popescu's example of hidden nonlocality [Phys. Rev. Lett. 74, 2619 (1995)], we elaborate on the conjecture that quantum states that are intuitively nonlocal, i.e., entangled, do not…
"Relative State" Formulation of Quantum Mechanics
The task of quantizing general relativity raises serious questions about the meaning of the present formulation and interpretation of quantum mechanics when applied to so fundamental a structure as…
Quantum superposition of distinct macroscopic states
Experimental evidence is presented that a superconducting quantum interference device (SQUID) can be put into a superposition of two magnetic-flux states: one corresponding to a few microamperes of current flowing clockwise, the other corresponding to the same amount ofCurrent flowing anticlockwise.
Elemental principles of t-topos
In this paper, a sheaf-theoretic approach toward fundamental problems in quantum physics is made. For example, the particle-wave duality depends upon whether or not a presheaf is evaluated at a…
Quantum mechanics without the projection postulate and its realistic interpretation
It is widely held that quantum mechanics is the first scientific theory to present scientifically internal, fundamental difficulties for a realistic interpretation (in the philosophical sense). The…
