Shake before use: universal enhancement of quantum thermometry by unitary driving
Emanuele Tumbiolo, Lorenzo Maccone, Chiara Macchiavello +2
Quantum thermometry aims at determining temperature with ultimate precision in the quantum regime. Standard equilibrium approaches, limited by the Quantum Fisher Information given…
Time-resolved characterization of pulsed squeezed light from a strongly driven silicon nitride microresonator
Emanuele Brusaschi, Marco Liscidini, Matteo Galli +2
Silicon nitride microresonators driven by strong pump pulses can generate squeezed light in a dominant spectral-temporal mode, a central resource for continuous-variable quantum co…
Photon triplets from integrated microrings: A path towards deterministic non-Gaussianity on a chip
Samuel E. Fontaine, J. E. Sipe, Marco Liscidini +1
We propose cascaded spontaneous four-wave mixing (SFWM) in microring resonators as a scalable and efficient approach for directly generating non-Gaussian states of light. Focusing…
An asymptotic field approach for the control of dipole emission in integrated structures
Vincenzo Macrì, Alice Viola, Marco Liscidini
We present a general framework to model spontaneous emission in integrated photonic structures by exploiting quantization of the electromagnetic field in terms of asymptotic in/out…
Time-resolved certification of frequency-bin entanglement over multi-mode channels
Stéphane Vinet, Marco Clementi, Marcello Bacchi +7
Frequency-bin entangled photons can be efficiently produced on-chip which offers a scalable, robust and low-footprint platform for quantum communication, particularly well-suited f…
Quantum optical shallow networks
Simone Roncallo, Angela Rosy Morgillo, Seth Lloyd +2
Classical shallow networks are universal approximators. Given a sufficient number of neurons, they can reproduce any continuous function to arbitrary precision, with a resource cos…
Quantum stroboscopy for time measurements
Seth Lloyd, Lorenzo Maccone, Lionel Martellini +1
Mielnik's cannonball argument uses the Zeno effect to argue that projective measurements for time of arrival are impossible. If one repeatedly measures the position of a particle (…
Time correlations from steady-state expectation values
Wojciech Górecki, Simone Felicetti, Lorenzo Maccone +1
Recovering properties of correlation functions is typically challenging. On the one hand, experimentally, it requires measurements with a temporal resolution finer than the system'…
Generation of hyperentangled photon pairs in the time and frequency domain on a silicon photonic chip
Sara Congia, Massimo Borghi, Emanuele Brusaschi +10
Multi-dimensional entangled photon states represent an important resource in quantum communication networks. Specifically, hyperentangled states presenting simultaneous entanglemen…
Prepare-and-Magic: Semi-Device Independent Magic Certification in the Prepare-and-Measure Scenario
Santiago Zamora, Rafael A. Macedo, Tailan S. Sarubi +3
Non-stabilizerness is an essential resource for quantum computational advantage, as stabilizer states admit efficient classical simulation. We develop a semi-device-independent fra…
Experimental verification of Threshold Quantum State Tomography on a fully-reconfigurable photonic integrated circuit
Eugenio Caruccio, Diego Maragnano, Giovanni Rodari +12
Reconstructing the state of a complex quantum system represents a pivotal task for all quantum information applications, both for characterization purposes and for verification of…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Learning Time-Varying Gaussian Quantum Lossy Channels
Angela Rosy Morgillo, Stefano Mancini, Massimiliano F. Sacchi +1
Time-varying quantum channels are essential for modeling realistic quantum systems with evolving noise properties. Here, we consider Gaussian lossy channels varying from one use to…

Massimiliano F. Sacchi
I investigate the problem of optimally discriminating between two open quantum dynamical processes in a single-shot scenario, with the goal of minimizing the error probability of i…
Beyond asymptotic scaling: Comparing functional quantum linear solvers
Andreea-Iulia Lefterovici, Michael Perk, Debora Ramacciotti +3
Solving systems of linear equations is a key subroutine in many quantum algorithms. In the last 15 years, many quantum linear solvers (QLS) have been developed, competing to achiev…
Enhanced Compressive Threshold Quantum State Tomography for Qudit Systems
Giovanni Garberoglio, Maurizio Dapor, Diego Maragnano +2
We propose an efficient quantum state tomography method inspired by compressed sensing and threshold quantum state tomography that can drastically reduce the number of measurement…
Bosonic two-stroke heat engines with polynomial nonlinear coupling
Giovanni Chesi, Chiara Macchiavello, Massimiliano Federico Sacchi
We study the thermodynamics of two-stroke heat engines where two bosonic modes and are coupled by the general nonlinear interaction $V_θ = \exp {(θa^{\dagger n}b^m -θ^* a^n…
Quantum interference with time-frequency modes and multiple-photons generated by a silicon nitride microresonator
Massimo Borghi, Emanuele Brusaschi, Marco Liscidini +2
We demonstrate bipartite gaussian boson sampling with squeezed light in 6 mixed time-frequency modes. Non-degenerate two-mode squeezing is generated in two time-bins from a silicon…
Quantum frequency resampling
Emanuele Tumbiolo, Simone Roncallo, Chiara Macchiavello +1
In signal processing, resampling algorithms can modify the number of resources encoding a collection of data points. Downsampling reduces the cost of storage and communication, whi…
