- Weshow that paradoxical consequences of violations of Bell's inequality areinduced by the use of an unsuitable probabilistic description forthe EPR-Bohm-Bell experiment. The conventional description (due to Bell) isbased on a combination of statistical data collected for differentsettings of polarization beam splitters (PBSs). In fact, such dataconsists of some conditional probabilities which only partially define aprobability space. Ignoring this conditioning leads to apparent contradictions inthe classical probabilistic model (due to Kolmogorov). We show howto make a completely consistent probabilistic model by taking intoaccount the probabilities of selecting the settings of the PBSs.Our model matches both the experimental data and is consistentwith classical probability theory.

- This year in Växjö we thought we would try an experiment—it felt high timefor a new result. Much of the foundations discussion ofprevious years has focussed on EPR-style arguments and the meaningand experimental validity of various Bell inequality violations. Yet, thereis another pillar of the quantum foundations puzzle that hashardly received any attention in our great series of meetings:It is the phenomenon first demonstrated by Kochen and Specker,quantum contextuality. Recently there has been a rapid growth ofactivity aimed toward better understanding this aspect of quantum mechanics,which Asher Peres sloganized by the phrase, “unperformed experiments haveno results.” Below is a sampling of some important paperson the topic for the reader not yet familiar withthe subject. What is the source of this phenomenon? Doesit depend only on high level features of quantum mechanics,or is it deep in the conceptual framework on whichthe theory rests? Might it, for instance, arise from theway quantum mechanics amends the classic laws of probability? Whatare the mathematically simplest ways contextuality can be demonstrated? Howmight the known results be made amenable to experimental tests?These were the sorts of discussions we hoped the sessionwould foster.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This study considers implementations of error correction in a simulation language on a classical computer. Error correction will be necessarily in quantum computing and quantum information. We will give some examples of the implementations of some error correction codes.These implementations will be made in a more general quantum simulation language on a classical computer in the language Mathematica. The intention of this research is to develop a programming language that is able to make simulations of all quantum algorithms and error corrections in the same framework. The program code implemented on a classical computer will provide a connection between the mathematical formulation of quantum mechanics and computational methods. This gives us a clear uncomplicated language for the implementations of algorithms.

Konferensbidrag (refereegranskat)abstract
- This paper approaches the interpretation of Quantum Mechanics as a set of directions for use and draws conclusions concerning its description of reality. It is argued that both the individual state function and the quantum information acquired by an observer are features of reality.
