Interferometry with Two Pairs of Spin Correlated Photons (2010)
Pavicic, Mladen, Summhammer, Johann
We propose a new experiment employing two independent sources of spin correlated photon pairs. Two photons from different unpolarized sources each pass through a polarizer to a detector. Although...

(to whom correspondence should be directed) We review and extend recent findings of Godsil and Zaks [1], who published a constructive coloring of the rational unit sphere with the property that for...
Summhammer, Johann, Bernroider, Gustav
We investigate the effects of a quantum entanglement regime within an ion conducting molecule (ion channel) of the neuronal plasma membrane on the onset dynamics of propagating nerve pulses (action...

Colouring the rational quantum sphere and the Kochen–Specker theorem (2007)
Hans Havlicek, Günther Krenn, Johann Summhammer
We review and extend recent findings of Godsil and Zaks, who published a constructive colouring of the rational unit sphere with the property that for any orthogonal tripod formed by rays extending...
Coloring the Rational Quantum Sphere and the Kochen-Specker Theorem (2007)
Hans Havlicek, Günther Krenn, Johann Summhammer, Karl Svozil
We review and extend recent ndings of Godsil and Zaks [1], who published a constructive coloring of the rational unit sphere with the property that for any orthogonal tripod formed by rays extending...
Quantum Theory as Efficient Representation of Probabilistic Information (2007)
Quantum experiments yield random data. We show that the most efficient way to store this empirical information by a finite number of bits is by means of the vector of square roots of observed...
Quantum Cooperation of Two Insects (2005)
The physical concept of quantum entanglement is brought to the biological domain. We simulate the cooperation of two insects by hypothesizing that they share a large number of quantum entangled...
Dialogue on Classical and Quantum between mathematician and experimenter (2001)
Khrennikov, Andrei, Summhammer, Johann
This dialogue took place at V\"axj\"o, 19 November 2001. The main aim of our meeting in V\"axj\"o was to clarify our viewpoints on foundations of quantum mechanics. The most attractive in our...
Structure of Probabilistic Information and Quantum Laws (2001)
In quantum experiments the acquisition and representation of basic experimental information is governed by the multinomial probability distribution. There exist unique random variables, whose...
Invariants of Elementary Observations (2000)
As physics searches for invariants in observations, this paper looks for invariants of probabilistic observation without assuming physical structure. Structure emerges from the basic assumption of...
Interferrometric Information Gain Versus Interaction-Free Measurement (2000)
Günther Krenn, Johann Summhammer, Karl Svozil, Viena Austria, ...
Interaction-free measurementschemes with ideal Mach-Zehnder interferometers promised to distinguish absorptive samples with lower average absorption than simple transmission schemes. Weshow that this...
Coloring the rational quantum sphere and the Kochen-Specker theorem (1999)
Havlicek, Hans, Krenn, Guenther, Summhammer, Johann, Svozil, Karl
We review and extend recent findings of Godsil and Zaks, who published a constructive coloring of the rational unit sphere with the property that for any orthogonal tripod formed by rays extending...
Maximum predictive power and the superposition principle (1999)
Recently, there has been a discussion on the origin of the quantum probability rules (Deutsch quant-ph/9906015, Polley quant-ph/9906124, Barnum et al. quant-ph/9907024, Finkelstein quant-ph/9907004)....
Factoring and Fourier Transformation with a Mach-Zehnder Interferometer (1997)
The scheme of Clauser and Dowling (Phys. Rev. A 53, 4587 (1996)) for factoring $N$ by means of an N-slit interference experiment is translated into an experiment with a single Mach-Zehnder...
Experiment on Interaction-Free Measurement in Neutron Interferometry (1997)
Hafner, Meinrad, Summhammer, Johann
A neutron interferometric test of interaction-free detection of the presence of an absorbing object in one arm of a neutron interferometer has been performed. Despite deviations from the ideal...
