Here we hypothesize that qualia are generated in the brain during the quantum computational resolution of difficult inverse problems when non-Clifford magic states are consumed above a threshold rate. Magic states are a well-known quantum resource necessary for universal quantum computation—a form of computational fuel. Inverse problems in cognition, such as reconstructing the state of the environment or internal states from incomplete or noisy sensory and interoceptive data, are typically ill-posed and computationally costly. A prototypical inverse problem is determining the actual 3D shape of an object from a blurry 2D retinal image. The Qualia-from-Quantum-Magic Hypothesis reframes classic philosophical thought experiments (e.g., zombies and inverted qualia), predicts when and where qualia should arise, and offers a natural explanation for their absence in simple systems such as thermostats and in many complex systems such as the Internet. In the brain, it predicts consciousness-related activity to be concentrated in the posterior sensory cortices, because vision and hearing pose some of the most challenging inverse problems that are vital to an animal’s survival. In light of this prediction, we conclude by discussing recent empirical findings of the Cogitate Consortium.Article Detecting quantum phase transitions in a frustrated spin chain via transfer learning of a quantum classifier algorithm(Physical Review A, 2024-05-20) Ferreira-Martins, André Juan; Silva, Leandro; Palhares Júnior, Alberto Bezerra de; Pereira, Rodrigo; Soares-Pinto, Diogo O.; Araújo, Rafael Chaves Souto; Canabarro, AskeryThe classification of phases and the detection of phase transitions are central and challenging tasks in diverse fields. Within physics, these rely on the identification of order parameters and the analysis of singularities in the free energy and its derivatives. Here, we propose an alternative framework to identify quantum phase transitions. Using the axial next-nearest-neighbor Ising (ANNNI) model as a benchmark, we show how machine learning can detect three phases (ferromagnetic, paramagnetic, and a cluster of the antiphase with the floating phase). Employing supervised learning, we demonstrate the feasibility of transfer learning. Specifically, a machine trained only with nearest-neighbor interactions can learn to identify a new type of phase occurring when next-nearest-neighbor interactions are introduced. We also compare the performance of common classical machine learning methods with a version of the quantum nearest neighbors (QNN) algorithmArticle Synthesis and characterization of poly(ethyl methacrylate-co-methacrylic acid) magnetic particles via miniemulsion polymerization(Elsevier B. V. Ltda, 2006-10-18) Araújo, José Humberto de; Nunes, J. S.; Vasconcelos, C. L. de; Cabral, F. A. O.; Pereira, M. R.; Fonseca, J. L. C.Magnetic particles are very important systems with potential use in drug delivery systems, ferrofluids, and effluent treatment. In many situations, such as in biomedical applications, it is necessary to cover inorganic magnetic particles with an organic material, such as polymers. In this work, latices based on magnetite covered by poly(ethyl methacrylate-co-methacrylic acid) were obtained via miniemulsion polymerization. The resultant latices had particles in the nanometric range and presented a pronounced superparamagnetic behavior.Article Effect of High Energy Milling on the Magnetic Properties of the WC-10wt.%Co Cemented Carbides(Materials Science Forum, 2006-01) Araujo, Jose Humberto; Manuel, Joao Baptista; Costa, F. A.; Macedo, Harim Revoredo de; Gomes, Uilame Umbelino; Silva, Angelus Giuseppe Pereira daCemented tungsten carbides were produced by liquid-phase sintering. In these work high energy milling (HEM) was used to produce homogeneous and finely grained powder mixtures. The milling effect in the magnetic properties of sintered samples is studied. Differents mixtures in same composition (WC-10wt%Co) were prepared by conventional mixture technique and wet HEM up to 300 hs in planetary Mill. Magnetic hysteresis measurements on the sintered samples detected a significant increase in the coercitive field and a decrease in the saturation magnetization with milling time increasing. X-ray diffractogram show phase transformations with milling time. The Magnetic properties are correlated with phase relations and microstructural properties of the sintered samples.Article Mössbauer study of spin-glass Fe x Zn1−x F2 system(Hyperfine Interaction, 1991-11) Araújo, Jose Humberto de; Cunha, Joao Batista Marimon da; Vasquez, A.; Amaral, L.; Moro, J. T.; Montenegro, F. C.; Rezende, S. M.; Coutinho-Filho, Mauricio D.57Fe Mössbauer effect measurements in the diluted Ising antiferromagnet Fe x Zn1−x F2 withx=0.25 andx=0.57 at temperatures between 4.2 and 55 K, are reported. DC suceptibility measurements show a spin-glass (SG) phase at low temperatures forx≤0.31. Our Mössbauer spectra show a phase transition to a SG state with antiferromagnetic order (AFSG) forx=0.25 and only antiferromagnetic order forx=0.57.
