Experimental property-reconstruction in a photonic quantum extreme learning machine
Alessia Suprano, Danilo Zia, Luca Innocenti +10
Recent developments have led to the possibility of embedding machine learning tools into experimental platforms to address key problems, including the characterization of the prope…
Quantum scrambling via accessible tripartite information
Gabriele Lo Monaco, Luca Innocenti, Dario Cilluffo +3
Quantum information scrambling (QIS), from the perspective of quantum information theory, is generally understood as local non-retrievability of information evolved through some dy…
Variational Gibbs State Preparation on NISQ devices
Mirko Consiglio, Jacopo Settino, Andrea Giordano +6
The preparation of an equilibrium thermal state of a quantum many-body system on noisy intermediate-scale quantum (NISQ) devices is an important task in order to extend the range o…
Temperature gradient and asymmetric steady state correlations in dissipatively coupled cascaded optomechanical systems
Claudio Pellitteri, G. Massimo Palma, Salvatore Lorenzo
The interaction between a light mode and a mechanical oscillator via radiation pressure in optomechanical systems is an excellent platform for a multitude of applications in quantu…
Entangled States are Harder to Transfer than Product States
Tony J. G. Apollaro, Salvatore Lorenzo, Francesco Plastina +2
The distribution of entangled states is a key task of utmost importance for many quantum information processing protocols. A commonly adopted setup for distributing quantum states…
Shadow tomography on general measurement frames
Luca Innocenti, Salvatore Lorenzo, Ivan Palmisano +4
We provide a new perspective on shadow tomography by demonstrating its deep connections with the general theory of measurement frames. By showing that the formalism of measurement…
Potential and limitations of quantum extreme learning machines
Luca Innocenti, Salvatore Lorenzo, Ivan Palmisano +3
Quantum reservoir computers (QRC) and quantum extreme learning machines (QELM) aim to efficiently post-process the outcome of fixed -- generally uncalibrated -- quantum devices to…
Quantum transfer of interacting qubits
Tony J. G. Apollaro, Salvatore Lorenzo, Francesco Plastina +2
The transfer of quantum information between different locations is key to many quantum information processing tasks. Whereas, the transfer of a single qubit state has been extensiv…
Quantum synchronisation and clustering in chiral networks
Salvatore Lorenzo, Benedetto Militello, Anna Napoli +2
We study the emergence of synchronisation in a chiral network of harmonic oscillators. The network consists of a set of locally incoherently pumped harmonic oscillators coupled pai…
Exotic interactions mediated by a non-Hermitian photonic bath
Federico Roccati, Salvatore Lorenzo, Giuseppe Calajò +3
Photon-mediated interactions between quantum emitters in engineered photonic baths is an emerging area of quantum optics. At the same time, non-Hermitian (NH) physics is currently…
Quantum collision models: open system dynamics from repeated interactions
Francesco Ciccarello, Salvatore Lorenzo, Vittorio Giovannetti +1
We present an extensive introduction to quantum collision models (CMs), also known as repeated interactions schemes: a class of microscopic system-bath models for investigating ope…
Microscopic biasing of discrete-time quantum trajectories
Dario Cilluffo, Igor Lesanovsky, Giuseppe Buonaiuto +5
We develop a microscopic theory for biasing the quantum trajectories of an open quantum system, which renders rare trajectories typical. To this end we consider a discrete-time qua…
Collisional picture of quantum optics with giant emitters
Dario Cilluffo, Angelo Carollo, Salvatore Lorenzo +3
The effective description of the weak interaction between an emitter and a bosonic field as a sequence of two-body collisions provides a simple intuitive picture compared to tradit…
Intermittent decoherence blockade in a chiral ring environment
Salvatore Lorenzo, Stefano Longhi, Albert Cabot +2
It has long been recognized that emission of radiation from atoms is not an intrinsic property of individual atoms themselves, but it is largely affected by the characteristics of…
Topological Protection and Control of Quantum Markovianity
Gian Luca Giorgi, Salvatore Lorenzo, Stefano Longhi
Under the Born--Markov approximation, a qubit system, such as a two-level atom, is known to undergo a memoryless decay of quantum coherence or excitation when weakly coupled to a f…

We study the dynamics of correlations in a paradigmatic setup to observe -symmetric physics: a pair of coupled oscillators, one subject to a gain one to a loss. Start…
Reading a qubit quantum state with a quantum meter: time unfolding of quantum Darwinism and quantum information flux
Salvatore Lorenzo, Mauro Paternostro, G. Massimo Palma
Quantum non Markovianity and quantum Darwinism are two phenomena linked by a common theme: the flux of quantum information between a quantum system and the quantum environment it i…
Multipartite entanglement transfer in spin chains
Tony J. G. Apollaro, Claudio Sanavio, Wayne Jordan Chetcuti +1
We investigate the transfer of genuine multipartite entanglement across a spin-1/2 chain with nearest-neighbor XX-type interaction. We focus on the perturbative regime, where a blo…
