Fuzzy Logic Behavior of Quantum-Controlled Braitenberg Vehicle Agents

Abstract : The behavior of agents represented by Braitenberg vehicles is investigated in the context of the quantum robot paradigm. The agents are processed through quantum circuits with fuzzy inputs, this permits to enlarge the behavioral possibilities and the associated decisions for these simple vehicles. The logical formulation Eigenlogic, using quantum logical observables as propositions and eigenvalues as truth values is applied in this investigation. Fuzzy logic arises naturally in this formulation when considering input states that are not eigenvectors of the logical observables, the fuzzy membership being the quantum mean value of the logical observable on the input state. Computer simulations permits visualization of complex behaviors resulting from the multiple combination of quantum control gates. This allows the detection of new Braitenberg vehicle behavior patterns related to identified emotions and linked to quantum-like effects.
