Learning functions of quantum states with distributed architectures
Marta Gili, Eliana Fiorelli, Ane Blázquez-García +2
Distributed architectures are gaining prominence in quantum machine learning as a means to overcome hardware limitations and enable scalable quantum information processing. In this…
Error recovery protocols within metastable Decoherence-Free Subspaces
Thomas Botzung, Eliana Fiorelli
Open quantum systems governed by quantum master equations can exhibit quantum metastability, where decoherence-free subspaces (DFS) remain approximately invariant for long transien…
Theoretical framework for quantum associative memories
Adrià Labay-Mora, Eliana Fiorelli, Roberta Zambrini +1
Associative memory refers to the ability to relate a memory with an input and targets the restoration of corrupted patterns. It has been intensively studied in classical physical s…
Signatures of associative memory behavior in a multi-mode spin-boson model
Eliana Fiorelli, Matteo Marcuzzi, Pietro Rotondo +2
Spin-boson models can describe a variety of physical systems, such as atoms in a cavity or vibrating ion chains. In equilibrium these systems often feature a radical change in thei…
Critical slowing down and entanglement protection
Eliana Fiorelli, Alessandro Cuccoli, Paola Verrucchi
We consider a quantum device interacting with a quantum many-body environment which features a second-order phase transition at . Exploiting the description of the cri…
Two-qubits in a large-S environment
Eliana Fiorelli, Alessandro Cuccoli, Paola Verrucchi
We analytically express the loss of entanglement between the components of a quantum device due to the generation of quantum correlations with its environment, and show that such l…
