Over the previous few years, researchers have been attempting to use quantum physics principle to quite a lot of fields, together with robotics, biology and cognitive science. Computational strategies that draw inspiration from quantum methods, often known as quantum-like (QL) fashions, might doubtlessly obtain higher efficiency and extra subtle capabilities than extra typical approaches.
Researchers at College of Genoa, in Italy, have not too long ago investigated the feasibility of utilizing a QL strategy to boost a robotic’s sensing capabilities. Of their paper, pre-published on arXiv, they current the outcomes of a case examine the place they examined a QL notion mannequin on a robotic with restricted sensing capabilities inside a simulated atmosphere.
“The thought for this examine got here to me after studying an article written in 1993 by Anton Amann, (‘The Gestalt problem in quantum theory‘) during which he in contrast the issue of Gestalt notion with the attribution of molecular form in quantum physics,” Davide Lanza, one of many researchers who carried out the examine, informed TechXplore. “I used to be amazed by this parallel between cognition and quantum phenomena, and I found then the flourishing discipline of quantum cognition research.”
Impressed by the concepts introduced by Amann, Lanza reached out to his supervisor Fulvio Mastrogiovanni and requested him whether or not he might examine the usage of quantum cognition modeling to boost robotic notion as a part of his grasp’s thesis. As soon as Mastrogiovanni permitted his thought, he began defining a preliminary mannequin to check the feasibility of utilizing a QL strategy in robotics, in collaboration with Paolo Solinas, a physics professor specialised in quantum computing working at College of Genoa.
As an preliminary step of their analysis, Lanza and Solinas outlined a simplified case examine the place a robotic ought to be capable of detect whether or not an object is positioned in entrance of it or behind its again. Their purpose was to research how a QL mannequin would take care of uncertainty and notion disambiguation on this easy state of affairs, which concerned a alternative between two choices (i.e., entrance or again), earlier than making use of it to extra advanced situations.
“We saved the data collected by the robotic’s sensor in a single qubit,” Lanza defined. “The qubit was allowed to have the 2 ‘entrance’ and ‘again’ states in a coherent superposition, enabling uncertainty modeling for blended ‘front-back’ conditions. Subsequently, when the qubit is measured, it returns a studying with a chance that’s associated to this superposition.”
When the researchers examined a QL notion mannequin in a simulation of the case examine they outlined, they discovered that it carried out comparably to non-quantum strategies. Nevertheless, the mannequin solely carried out effectively when it was examined utilizing a quantum simulator referred to as QASM, which emulates the execution of quantum circuits on a classical computing gadget.
Truly implementing the mannequin on the IBM Quantum Expertise (IBMQ) platform, alternatively, resulted in a variety of errors, notably in trials the place the article was in an ambiguous place (i.e., when it was not so clear whether or not it was in entrance or behind the robotic). Lanza, Solinas and Mastrogiovanni thus argue that QL notion fashions may very well be examined extra successfully in simulations, as realizations on quantum backends can result in a variety of errors in unbalanced conditions.
“Utilizing a qubit is, for my part, a extra compact and stylish answer for notion and cognition modeling,” Lanza mentioned. “Certainly, a qubit inherently supplies attention-grabbing modeling options typical of quantum systems, without having of additional modules to take care of probabilistic outcomes.”
The current paper printed on arXiv is merely the primary a part of the challenge carried out by Lanza, Solinas and Mastrogiovanni. The researchers at the moment are exploring the opportunity of making use of the identical QL mannequin to extra advanced situations, whereas additionally testing it in simulations involving robots with multiple integrated sensors.
The findings they gathered up to now spotlight the potential of introducing fashions primarily based on quantum theory in robotics analysis. Sooner or later, they may encourage different analysis groups to use QL fashions of human cognition to robotics issues and consider their efficiency.
“After this preliminary examine, we began engaged on multisensorial integration, growing a model for a number of sensors capable of interpolate the info and absolutely exploit quantum options,” Lanza mentioned.
