Demonstration of Cognitive Bias on a Noisy Intermediate-Scale Quantum Processor

Fabio Antonio Bovino1, Alessandro Comi2

1Sapienza University of Rome, Italy; 2TIM S.p.A.

The decision-making process of the individual is analogous to the collapse of a quantum system at the moment of measurement, whereby quantum system we mean the decision-maker, his mental processes and the environmental context that influences him in his choices. Classical probability depends on the lack of information, quantum probability is instead intrinsic to the system to be studied, meaning that the system, consisting of the decision-maker and the context, is in a superposition of states, each with its own amplitude of probability. Only the measurement process (the decision) selects in the decision maker a specific state among those in which he was overlapping. We demonstrated on a Noisy Intermediate –Scale Quantum Processor the model of the “order effect”, one of the most important cognitive bias.

THz frequency combs form dispersion-compensated antenna-coupled ring quantum cascade lasers

Paolo Micheletti1, Urban Senica1, Andres Forrer1, Sara Cibella2, Giudo Torrioli2, Mattias Beck1, Jerome Faist1, Giacomo Scalari1

1Institute of Quantum Electronics, Physics Department, ETH Zurich, Zurich, Switzerland; 2CNR-Istituto di Fotonica e Nanotecnologie, Rome, Italy

We report comb operation of RF injected ring Quantum Cascade Lasers. A coupled waveguide approach is implemented for dispersion compensation while passive bullseye antenna improves the device power extraction and far field. Phase sensitive measurements are presented which hints at the presence of soliton state.

Nature engineered metasurfaces: spin-to-orbital angular momentum conversion in diatom frustules

Edoardo De Tommasi, Maria Antonietta Ferrara, Giuseppe Coppola, Gianluigi Zito

CNR-ISASI, Italy

Evolution provided, through eras, several animal, vegetal, and protist species with sub-micrometric constituent structures able to manipulate light at the nanoscale in non trivial ways. In particular, diatoms are single-celled microalgae enclosed in a porous silica shell, the frustule, perforated by regular patterns of micro- and nano-pores and whose functionalities comprise mechanical stability, sorting of nutrients from harmful agents and optimization of sunlight harvesting. Photonic properties of frustules include focusing, photoluminescence, and optical activity, among others. In the present work we show preliminary results concerning the ability of single valves of Arachnoidiscus ehrenbergii diatom frustules to manipulate incoming, circularly polarized radiation in such a way to generate light beams provided with orbital angular momentum (optical vortices). The combination of cross-polarization imaging in different spectral ranges, polarization sensitive digital holographic imaging (PSDHI), and interferometry allowed characterizing the valves and detecting the presence of spin-orbit coupling induced by their ultrastructure.
