Journal: NATURE Publication date: 2023/05/25 DOI: 10.1038/s41586-023-05917-9 Abstract: During their thermally pulsing phase, asymptotic giant branch (AGB) stars eject material that forms extended dusty envelopes(1). Visible polarimetric imaging found [...]

Journal: SCIENTIFIC REPORTS Publication date: 2023/06/05 DOI: 10.1038/s41598-023-35867-1 Abstract: We propose quantum neural networks that include multi-qubit interactions in the neural potential leading to a reduction of the network depth without losing approximative power. We show that the presence of multi-qubit potentials in the quantum perceptrons enables more [...]

Authors: Concha, D.; Pereira, L.; Zambrano, L.; Delgado, A. Journal: SCIENTIFIC REPORTS Publication date: 2023/05/08 DOI: 10.1038/s41598-023-34327-0 Abstract: Here, we study the problem of decoding information transmitted through unknown quantum states. We assume that Alice encodes an alphabet into a set of orthogonal quantum states, which are then transmitted to Bob. However, the quantum channel [...]

We investigate a light-matter interface based on the photonic counterpart of these states and prove that [...]

Authors: Mousavi, S. V.; Miret-Artes, S. Journal: SYMMETRY-BASEL Publication date: 2023/06/01 DOI: 10.3390/sym15061184 Abstract: In this work, we proposed a smooth transition wave equation from a quantum to classical regime in the framework of von Neumann formalism for ensembles and then obtained an equivalent scaled equation. This led us to develop a scaled statistical theory [...]
