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…
Quantum fluctuation dynamics of open quantum systems with collective operator-valued rates, and applications to Hopfield-like networks
Eliana Fiorelli
We consider a class of open quantum many-body systems that evolves in a Markovian fashion, the dynamical generator being in GKS-Lindblad form. Here, the Hamiltonian contribution is…
Mean-field dynamics of open quantum systems with collective operator-valued rates: validity and application
Eliana Fiorelli, Markus Müller, Igor Lesanovsky +1
We consider a class of open quantum many-body Lindblad dynamics characterized by an all-to-all coupling Hamiltonian and by dissipation featuring collective ``state-dependent" rates…
Optimal storage capacity of quantum Hopfield neural networks
Lukas Bödeker, Eliana Fiorelli, Markus Müller
Quantum neural networks form one pillar of the emergent field of quantum machine learning. Here, quantum generalisations of classical networks realizing associative memories - capa…
Stochastic entropy production: Fluctuation relation and irreversibility mitigation in non-unital quantum dynamics
Eliana Fiorelli, Stefano Gherardini, Stefano Marcantoni
In this work, we study the stochastic entropy production in open quantum systems whose time evolution is described by a class of non-unital quantum maps. In particular, as in [Phys…
Phase diagram of quantum generalized Potts-Hopfield neural networks
Eliana Fiorelli, Igor Lesanovsky, Markus Müller
We introduce and analyze an open quantum generalization of the q-state Potts-Hopfield neural network, which is an associative memory model based on multi-level classical spins. The…
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…
Dynamics of strongly coupled disordered dissipative spin-boson systems
Eliana Fiorelli, Pietro Rotondo, Federico Carollo +2
Spin-boson Hamiltonians are an effective description for numerous quantum many-body systems such as atoms coupled to cavity modes, quantum electrodynamics in circuits and trapped i…
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…
Quantum accelerated approach to the thermal state of classical spin systems with applications to pattern-retrieval in the Hopfield neural network
Eliana Fiorelli, Pietro Rotondo, Matteo Marcuzzi +2
We explore the question as to whether quantum effects can yield a speedup of the non-equilibrium evolution of spin systems towards a classical thermal state. In our approach we exp…
