Project: Quantum Information Access and Retrieval Theory (QUARTZ)

Quantum Information Access and Retrieval Theory (QUARTZ) is a project that aims to educate early stage researchers to adopt a novel, theoretically and empirically motivated approach to information access and retrieval, based on the quantum mechanical framework.

More about the project

The project will concern applications of the mathematical formalism of quantum theory (especially quantum probability and information) to model the process of decision making. It will involve the study of probabilistic, informational, cognitive and psychological aspects of general theory of decision making in the quantum-like framework by using, in particular, theory of open quantum systems and quantum instruments.

The main aim is to proceed towards modeling of the decision making aspects of ranking in information access and retrieval. The doctoral student that will be engaged in the project will get a proper education in quantum information and quantum open systems. He/she will further explore this knowledge to model the process of decision making and adaptive ranking of information by using quantum Markov master equations. Even these approximate equations are very complicated and numerical methods will be widely used.

Expected results

  • Development of the general formalism of the theory of decision making based on quantum probability, quantum information and the theory of open quantum systems.
  • Methods of adaptive ranking of information (including algorithms and numerical simulation) based on quantum adaptive dynamics, which may lead to creation of novel algorithms for adaptive ranking of information.
