Selected papers on the EPR paradox, Bell
inequalities and completeness of QT.
Contextuality
as the Key to understand Quantum Paradoxes
Kupczynski M,arXiv:2005.06864 [quant-ph] 14 May
2020
This paper
contains a short
introduction and the
slides from our invited talks given in 2018 during the Advanced School
of Quantum
Foundations and Quantum Computation in Joao Pessoa , Brazil.
Is the Moon there when nobody
looks: Bell inequalities and physical reality
Kupczynski M. Front. Phys., 23
September 2020 | https://doi.org/10.3389/fphy.2020.00273
All speculations about quantum
nonlocality are based on incorrect mental pictures and incorrect
interpretations of QM.
Locally causal explanation of
quantum correlations in real spin polarisation correlation experiments is
given.
Quantum
mechanics and modeling of physical reality.
Kupczynski M .Phys Scr. (2018) 93:123001. doi: 10.1088/1402-4896/aae212
Some scientists and scientific
writers promote some exotic interpretations and evoke quantum magic.
Magical explanations are misleading
and counterproductive. We examine in detail when and how
a probabilistic
model may describe completely a random experiment and how the completeness
of quantum mechanics
should be tested.
Closing the door on quantum
non-locality
Kupczynski M. Entropy. (2018) 20:877.
doi: 10.3390/e20110877
Bell-type inequalities are proven
using oversimplified probabilistic models. If setting-dependent variables
describing measuring
instruments are correctly introduced, none of these inequalities may be proven.
In this paper, we discussing of
computer simulations of Bell tests the results which provide additional strong
arguments for closing the
door on quantum nonlocality.
Is Einsteinian no-signalling violated in Bell
tests?
Kupczynski M. Open
Physics. (2017) 15:739–753. doi: 10.1515/phys-2017-0087
We demonstrate how a particular
identification and selection procedures of paired distant outcomes
are the most probable
cause of the apparent violation of no-signalling. The outcomes of real
experiments
may be explained in locally causal
way without evoking spooky influences.
The Contextuality Loophole is Fatal for the
Derivation of Bell Inequalities
Nieuwenhuizen T.M. and Kupczynski
M. 2017, ,Foundations of Physics, 1-4,DOI
10.1007/s10701-017-0062-y
Bell model
does not incorporate setting dependent
variables describing the measuring instruments
What is
called by us the contextual loophole.
Comments
on New Ontology of Quantum Mechanics called CSM
M Kupczynski - arXiv: 1602.03495
A critical
analysis of CSM is given. QM is an epistemic theory.
EPR
Paradox, Quantum Nonlocality and Physical Reality
M Kupczynski - ,J. Phys.: Conf. Ser. 701 012021 (2016)
Several finite sample proofs of Bell-type
inequalities are critically analysed. We also
Explain how Bell’s
game is won in real experiments without the quantum magic.
On operational approach to entanglement and how to
certify it.
M.Kupczynski , International
Journal of Quantum Information, vol. 14, issue 4 (2016) arXiv:1602.00146
Entanglement is an important resource for quantum
information. Its meaning and the experiments used to certify it are discussed.
Greeks were right :
critical comments on Qbism
M Kupczynski - arXiv: 1505.
We give several arguments against the quantum Bayesianism (Qbism) .
Significance
tests and sample homogeneity loophole
M Kupczynski - arXiv:1505.06349
If the
homogeneity of data samples is not tested carefully enough then the results of
significance tests become meaningless.
Breakdown of
statistical inference from some random experiments
M Kupczynski and H.De Raedt - Computer Physics
Communications 200, 168 (2016)
arXiv:1411.7085
We study data generated by computer experiments
operating according to particular internal protocols.
We show
that the standard statistical analysis of a sample, containing 100 000 data
points or more, may sometimes be
highly misleading and statistical
errors largely underestimated…
Bell Inequalities,
Experimental Protocols and Contextuality.
M. Kupczynski, Found.Phys.2014 doi:10.1007/s10701-014-9863-4
We
discuss in detail an intimate relation between experimental protocols and
probabilistic models.
In particular we show that local realistic and
stochastic hidden variable models are inconsistent with the experimental
protocols
used in spin
polarization correlation experiments..
Causality and
local determinism versus quantum nonlocality
Kupczynski M 2014 J. Phys.: Conf. Ser.
504 012015
A probabilistic model is proposed to explain
quantum nonlocal correlations. It depends explicitly on the context of each
experiment and outcomes (clicks on the detectors) are
determined by supplementary local parameters describing both
physical signals and measuring
instruments.
Entanglement
and quantum nonlocality demystified
M Kupczynski – AIP Conf.Proc.1508.253(2012),
doi:10.1063/1.4773137
Quantum nonlocality is presented
often as the most remarkable and inexplicable
phenomenon known to modern science which was confirmed in the experiments
proving the
violation of Bell Inequalities. We oppose this point of view.
Time Series,
Stochastic Processes and Completeness of Quantum Theory
M Kupczynski - in Advances Quantum Theory ,
edited by G. Jaeger et al,.
AIP
Conference Proceedings 1327, American Institute of Physics, Melville, NY, 2011,
pp.394-400
A standard data analysis in terms of histograms and empirical frequency distributions does
not allow
to discover any fine structure in experimental time-series of data. To
discover such fine stochastic structures
more subtle tools are needed which are reviewed and discussed.
Is quantum theory predictably complete?
M Kupczynski - Phys.Scr.T135, 014005 (2009)
QM provides statistical
predictions for various physical phenomena. It is pointed out that we
don’t
even know whether QM is able to explain a fine structure of experimental
time series.
EPR paradox,
locality and completeness of quantum theory
M Kupczynski -
in Quantum Theory Reconsideration of
Foundations-4, edited by G.Adenier et al,
AIP
Conference Proceedings 962, American Institute of Physics, Melville, NY, 2007,
pp.274-85.
It is explained why the Bell
inequalities and their violation do not prove the completeness of QM.
Seventy years of the EPR paradox
M Kupczynski - in Albert Einstein Century International Conference edited by
by J-M Alimi and A Funzfa
,AIP Conference Proceedings 861, American Institute of Physics,
Melville, NY,2006,
pp.516-523.
The discussions following the famous EPR paper are reviewed and various points of
view critically analyzed.
Entanglement
and Bell inequalities
M Kupczynski - J.Russ.Laser Research 26, 514-23(2005)
The entangled quantum states play a key role in quantum information.
The
association of the quantum state vector with each individual physical system
in an attributive way is a source of many paradoxes and
inconsistencies.
Contextual
Observables and Quantum Information
M Kupczynski – arXiv:quant-ph/0408002, 2004 - arxiv.org
In this
short paper we present the main features of a new quantum
programming language
proposed recently by Peter Selinger which gives
a good idea about the
difficulties of constructing a scalable quantum computer.
On the
completeness of quantum mechanics
M Kupczynski – arXiv :quant-ph/0208061, 2002 -
arxiv.org
Quantum cryptography, quantum computer project, space-time
quantization
program and recent computer experiments reported by Accardi
and his collaborators show
the importance and actuality of the discussion of the completeness of quantum mechanics ...

A 121,
51-3(1987}
A new formulation of the deterministic local Pitovsky
model, able to reproduce the predictions
of quantum mechanics for distant spin polarization correlations and to.
M Kupczyński - Phys.Lett.A 121 ,
205-207(1987)
Bertrand's paradox from the theory of probability is recalled and its
relevance to the
impossibility of proving Bell's inequalities for realistic spin polarization
correlation experiments id discussed.
On some new tests of completeness of
quantum mechanics
M Kupczyński - Phys.Lett. A 116, p.417-419, (1986)
In order to test completeness of
QM we propose new efficient tests of experimental data.
New test of completeness of
quantum mechanics
M Kupczynski - ICTP preprint IC/84/242, 1984
- cds.cern.ch
New tests
are proposed and reasons for the violation of Bell inequalities are given
Is the Hilbert space language too rich?
M Kupczyński – Int.Journ.for Theor. Phys.10,297 (1974), reprinted in “ Physical Theory
as Lologico-Operational Structure”, ed.C.A.
Hooker, Reidel,Dordrecht,
1978,pp.89-113
In order to answer this question, we analyse different phenomena
occurring in
general experimental set-ups arranged to analyse the properties of some unknown
beams
of particles. We arrive at the conclusion that sometimes the Hilbert space
language is too rich.
