Classical Invasive Description of Informationally-Complete Quantum Processes
Moritz F. Richter, Andrea Smirne, Walter T. Strunz +1
In classical stochastic theory, the joint probability distributions of a stochastic process obey by definition the Kolmogorov consistency conditions. Interpreting such a process as…
Markovian master equations for quantum-classical hybrid systems
Alberto Barchielli
The problem of constructing a consistent quantum-classical hybrid dynamics is afforded in the case of a quantum component in a separable Hilbert space and a continuous, finite-dime…
Coin dimensionality as a resource in quantum metrology involving discrete-time quantum walks
Simone Cavazzoni, Luca Razzoli, Giovanni Ragazzi +2
We address metrological problems where the parameter of interest is encoded in the internal degree of freedom of a discrete-time quantum walker, and provide evidence that coin dime…
On the use of superthermal light for imaging applications
Silvia Cassina, Gabriele Cenedese, Marco Lamperti +2
Ghost imaging and differential ghost imaging are well-known imaging techniques based on the use of both classical and quantum correlated states of light. Since the existence of cor…

We consider quantum systems with a Hamiltonian containing a weak perturbation i.e. , $\boldsymbolλ= \{λ_1, λ_2,...\}…
Qibosoq: an open-source framework for quantum circuit RFSoC programming
Rodolfo Carobene, Alessandro Candido, Javier Serrano +3
We present Qibosoq, an open-source server-side software package designed for radio frequency system on chip (RFSoC) for executing arbitrary pulse sequences and algorithms on self-h…
Dissipation-induced collective advantage of a quantum thermal machine
Matteo Carrega, Luca Razzoli, Paolo Andrea Erdman +3
Do quantum correlations lead to better performance with respect to several different systems working independently? For quantum thermal machines, the question is whether a working…

We present Qibolab, an open-source software library for quantum hardware control integrated with the Qibo quantum computing middleware framework. Qibolab provides the software laye…
Multi-variable integration with a variational quantum circuit
Juan M. Cruz-Martinez, Matteo Robbiati, Stefano Carrazza
In this work we present a novel strategy to evaluate multi-variable integrals with quantum circuits. The procedure first encodes the integration variables into a parametric circuit…
Beating the standard quantum limit for binary phase-shift-keying discrimination with a realistic hybrid feed-forward receiver
Michele N. Notarnicola, Stefano Olivares
We propose a hybrid feed-forward receiver (HFFRE) for the discrimination of binary phase-shift-keyed coherent states based on the appropriate combination of a displacement feed-for…
Quantum Computing for High-Energy Physics: State of the Art and Challenges. Summary of the QC4HEP Working Group

Quantum computers offer an intriguing path for a paradigmatic change of computing in the natural sciences and beyond, with the potential for achieving a so-called quantum advantage…
Single Photon Superradiance and Subradiance as Collective Emission From Symmetric and Antisymmetric States
Nicola Piovella, Stefano Olivares
Recent works have shown that collective single photon spontaneous emission from an ensemble of resonant two-level atoms is a rich field of study. Superradiance describes emissi…
Universal stability of coherently diffusive 1D systems with respect to decoherence
F. S. Lozano-Negro, E. Alvarez Navarro, N. C. Chávez +4
Static disorder in a 3D crystal degrades the ideal ballistic dynamics until it produces a localized regime. This Metal-Insulator Transition is often preceded by coherent diffusion.…

Invasiveness of non-equilibrium quantum thermometry
Francesco Albarelli, Matteo G. A. Paris, Bassano Vacchini +1
One of the main advantages expected from using quantum probes as thermometers is non invasiveness, i.e., a negligible perturbation to the thermal sample. However, invasiveness is r…
