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...

and (2008)

Hans Havlicek, Günther Krenn, Johann Summhammer, Karl Svozil

(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...

Quantum entanglement in the voltage dependent sodium channel can reproduce the salient features of neuronal action potential initiation (2007)

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)

Summhammer, Johann

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)

Summhammer, Johann

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)

Summhammer, Johann

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)

Summhammer, Johann

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)

Summhammer, Johann

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)

Summhammer, Johann

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...
