Remark on multi-particle observables and entangled states with constant complexity
Dominik Janzing, Thomas Beth
We show that every density matrix of an n-particle system prepared by a quantum network of constant depth is asymptotically commuting with the mean-field observables. We introduce…
Causal vs. Anticausal merging of predictors
Sergio Hernan Garrido Mejia, Patrick Blöbaum, Bernhard Schölkopf +1
We study the differences arising from merging predictors in the causal and anticausal directions using the same data. In particular we study the asymmetries that arise in a simple…
Thermodynamic efficiency of information and heat flow
Armen E. Allahverdyan, Dominik Janzing, Guenter Mahler
A basic task of information processing is information transfer (flow). Here we study a pair of Brownian particles each coupled to a thermal bath at temperature and , res…
Identifying Finite Mixtures of Nonparametric Product Distributions and Causal Inference of Confounders
Eleni Sgouritsa, Dominik Janzing, Jonas Peters +1
We propose a kernel method to identify finite mixtures of nonparametric product distributions. It is based on a Hilbert space embedding of the joint distribution. The rank of the c…
Bounding probabilities of causation through the causal marginal problem
Numair Sani, Atalanti A. Mastakouri, Dominik Janzing
Probabilities of Causation play a fundamental role in decision making in law, health care and public policy. Nevertheless, their point identification is challenging, requiring stro…
Fragility of a class of highly entangled states of many quantum-bits
Dominik Janzing, Thomas Beth
We consider a Quantum Computer with n quantum-bits (`qubits'), where each qubit is coupled independently to an environment affecting the state in a dephasing or depolarizing way. F…
