Magnetic response and electronic states of well defined Graphene/Fe/Ir(111) heterostructure
Claudia Cardoso, Giulia Avvisati, Pierluigi Gargiani +7
We investigate a well defined heterostructure constituted by magnetic Fe layers sandwiched between graphene (Gr) and Ir(111). The challenging task to avoid Fe-C solubility and Fe-I…
Electron correlation effects in the exchange coupling at the Fe/CoO/Ag(001) ferro-/antiferro-magnetic interface
Marco Sbroscia, Adriano Verna, Giovanni Stefani +8
Angle resolved-Auger-photoelectron coincidence spectroscopy (AR-APECS) has been exploited to investigate the role that electron correlation plays in the exchange-coupling at the fe…
Unexpectedly large electron correlation measured in Auger spectra of ferromagnetic iron thin films: orbital-selected Coulomb and exchange contributions
R. Gotter, A. Verna, M. Sbroscia +7
A set of electron-correlation energies as large as 10 eV have been measured for a magnetic 2ML Fefilm deposited on Ag(001). By exploiting the spin selectivity in angle-resolved Aug…
Experimental characterization of the energetics of quantum logic gates
Valeria Cimini, Stefano Gherardini, Marco Barbieri +5
We characterize the energetic footprint of a two-qubit quantum gate from the perspective of non-equilibrium quantum thermodynamics. We experimentally reconstruct the statistics of…
Measuring the time-frequency properties of photon pairs: a short review
Ilaria Gianani, Marco Sbroscia, Marco Barbieri
Encoding information in the time-frequency domain is demonstrating its potential for quantum information processing. It offers a novel scheme for communications with large alphabet…
Adaptive Tracking of Enzymatic Reactions with Quantum Light
Valeria Cimini, Marta Mellini, Giordano Rampioni +4
Enzymes are essential to maintain organisms alive. Some of the reactions they catalyze are associated with a change in reagents chirality, hence their activity can be tracked by us…

Valeria Cimini, Ilaria Gianani, Marco Sbroscia +2
The superposition of quantum states lies at the heart of physics and has been recently found to serve as a versatile resource for quantum information protocols, defining the notion…
Quantum sensors for dynamical tracking of chemical processes
Valeria Cimini, Ilaria Gianani, Ludovica Ruggiero +7
Quantum photonics has demonstrated its potential for enhanced sensing. Current sources of quantum light states tailored to measuring, allow to monitor phenomena evolving on time sc…
Speed of qubit states during thermalisation
Michele Maria Feyles, Luca Mancino, Marco Sbroscia +2
Classifying quantum states usually demands to observe properties such as the amount of correlation at one point in time. Further insight may be gained by inspecting the dynamics in…
Assessing frequency correlation through a distinguishability measurement
Marco Sbroscia, Ilaria Gianani, Emanuele Roccia +4
The simplicity of a question such as wondering if correlations characterize or not a certain system collides with the experimental difficulty of accessing such information. Here we…
Bridging thermodynamics and metrology in non-equilibrium Quantum Thermometry
Vasco Cavina, Luca Mancino, Antonella De Pasquale +7
Single-qubit thermometry presents the simplest tool to measure the temperature of thermal baths with reduced invasivity. At thermal equilibrium, the temperature uncertainty is link…
Multiparameter quantum estimation of noisy phase shifts
Emanuele Roccia, Valeria Cimini, Marco Sbroscia +6
Phase estimation is the most investigated protocol in quantum metrology, but its performance is affected by the presence of noise, also in the form of imperfect state preparation.…
Realism-information complementarity in photonic weak measurements
Luca Mancino, Marco Sbroscia, Emanuele Roccia +4
The emergence of realistic properties is a key problem in understanding the quantum-to-classical transition. In this respect, measurements represent a way to interface quantum syst…
Geometrical bounds on irreversibility in open quantum systems
Luca Mancino, Vasco Cavina, Antonella De Pasquale +6
Clausius inequality has deep implications for reversibility and the arrow of time. Quantum theory is able to extend this result for closed systems by inspecting the trajectory of t…
Monitoring dispersive samples with single photons: the role of frequency correlations
Emanuele Roccia, Marco G. Genoni, Luca Mancino +3
The physics that governs quantum monitoring may involve other degrees of freedom than the ones initialised and controlled for probing. In this context we address the simultaneous e…
