Dynamical, thermal, and ground-state multiparameter quantum metrology: Fundamental limits and their attainability in magnetometry
Riccardo Pedroni, Víctor Izquierdo, Advay Burte +3
We consider the simultaneous estimation of multiple parameters in Hamiltonians of the form , where encodes the unknown parameters and $H…
Quantum steering in networks: Measurement-device-independent detection, continuous variables, and practical Gaussian schemes
Shao-Hua Hu, Chung-Yun Hsieh, Huan-Yu Ku +2
We consider quantum steering certification in multipartite networks, with a focus on minimal trust scenarios: all-except-one parties are untrusted and treated device-independently.…
Energy-Time-Accuracy Tradeoffs in Thermodynamic Computing
Alberto Rolandi, Paolo Abiuso, Patryk Lipka-Bartosik +3
In the paradigm of thermodynamic computing, instead of behaving deterministically, hardware undergoes a stochastic process in order to sample from a distribution of interest. While…
An information-theoretic proof of the Planckian bound for thermalization
Paolo Abiuso, Alberto Rolandi, John Calsamiglia +2
We demonstrate that quantum mechanics entails a fundamental lower bound on the thermalization time of any system. At finite temperature, we show that is bounded by half the…
Tight and self-testing multipartite quantum Bell inequalities from the renormalization group
Paolo Abiuso, Julian Fischer, Miguel Navascués
In past work, the concept of connectors was introduced: directed tensors with the property that any contraction thereof defines a multipartite quantum Bell inequality, i.e., a line…
From dynamical to steady-state many-body metrology: Precision limits and their attainability with two-body interactions
Ricard Puig, Pavel Sekatski, Paolo Andrea Erdman +3
We consider the estimation of an unknown parameter via a many-body probe. The probe is initially prepared in a product state and many-body time-independent interactions enhance…
Escaping the Shadow of Bell's Theorem in Network Nonlocality
Maria Ciudad Alañón, Emanuel-Cristian Boghiu, Paolo Abiuso +1
The possibility of nonclassicality in networks unrelated to Bell's original eponymous theorem has recently attracted significant interest. Here, we identify a sufficient condition…
Fundamental limits of metrology at thermal equilibrium
Paolo Abiuso, Pavel Sekatski, John Calsamiglia +1
We consider the estimation of an unknown parameter through a quantum probe at thermal equilibrium. The probe is assumed to be in a Gibbs state according to its Hamiltonian $H_θ…
Physicality of evolution and statistical contractivity are equivalent notions of maps
Matteo Scandi, Paolo Abiuso, Dario De Santis +1
Statistical quantifiers are generically required to contract under physical evolutions, following the intuition that information should be lost under noisy transformations. This pr…
Collective advantages in finite-time thermodynamics
Alberto Rolandi, Paolo Abiuso, Martí Perarnau-Llobet
A central task in finite-time thermodynamics is to minimize the excess or dissipated work when manipulating the state of a system immersed in a thermal bath. We cons…
Verification of Continuous-Variable Quantum Memories
Paolo Abiuso
A proper quantum memory is argued to consist in a quantum channel which cannot be simulated with a measurement followed by classical information storage and a final state preparati…
Quantum Fisher Information and its dynamical nature
Matteo Scandi, Paolo Abiuso, Jacopo Surace +1
The importance of the quantum Fisher information metric is testified by the number of applications that this has in very different fields, ranging from hypothesis testing to metrol…
Optimal Thermometers with Spin Networks
Paolo Abiuso, Paolo Andrea Erdman, Michael Ronen +3
The heat capacity of a given probe is a fundamental quantity that determines, among other properties, the maximum precision in temperature estimation. In turn, $\math…
Pareto-optimal cycles for power, efficiency and fluctuations of quantum heat engines using reinforcement learning
Paolo Andrea Erdman, Alberto Rolandi, Paolo Abiuso +2
The full optimization of a quantum heat engine requires operating at high power, high efficiency, and high stability (i.e. low power fluctuations). However, these three objectives…
Characterizing (non-)Markovianity through Fisher Information
Paolo Abiuso, Matteo Scandi, Dario De Santis +1
A non-isolated physical system typically loses information to its environment, and when such loss is irreversible the evolution is said to be Markovian. Non-Markovian effects are s…
Thermodynamics and optimal protocols of multidimensional quadratic Brownian systems
Paolo Abiuso, Viktor Holubec, Janet Anders +3
We characterize finite-time thermodynamic processes of multidimensional quadratic overdamped systems. Analytic expressions are provided for heat, work, and dissipation for any evol…

Zhuolin Ye, Federico Cerisola, Paolo Abiuso +3
We optimize finite-time stochastic heat engines with a periodically scaled Hamiltonian under experimentally motivated constraints on the bath temperature and the scaling parame…
Geometric optimization of non-equilibrium adiabatic thermal machines and implementation in a qubit system
Pablo Terren Alonso, Paolo Abiuso, Marti Perarnau-Llobet +1
We adopt a geometric approach to describe the performance of adiabatic quantum machines, operating under slow time-dependent driving and in contact to two or more reservoirs with a…
Single-photon nonlocality in quantum networks
Paolo Abiuso, Tamás Kriváchy, Emanuel-Cristian Boghiu +3
The state obtained when a single photon impinges on a balanced beamsplitter is often known as single-photon entangled and its nonlocal properties have been the subject of intense d…
Measurement-device-independent entanglement detection for continuous-variable systems
Paolo Abiuso, Stefan Bäuml, Daniel Cavalcanti +1
We study the detection of continuous-variable entanglement, for which most of the existing methods designed so far require a full specification of the devices, and we present proto…
Maximum power heat engines and refrigerators in the fast-driving regime
Vasco Cavina, Paolo A. Erdman, Paolo Abiuso +2
