Impact of Information on Quantum Heat Engines
Lindsay Bassman Oftelie, Michele Campisi
The emerging field of quantum thermodynamics is beginning to reveal the intriguing role that information can play in quantum thermal engines. Information enters as a resource when…
Overcoming disorder in superconducting globally driven quantum computing
Riccardo Aiudi, Julien Despres, Roberto Menta +5
We study the impact of static disorder on a globally-controlled superconducting quantum computing architecture based on a quasi-two-dimensional ladder geometry [R. Menta et al., Ph…
Quantifying complexity of continuous-variable quantum states via Wehrl entropy and Fisher information
Siting Tang, Francesco Albarelli, Yue Zhang +2
The notion of complexity of quantum states is quite different from uncertainty or information contents, and involves the tradeoff between its classical and quantum features. In thi…
Statistical Characterization of Entanglement Degradation Under Markovian Noise in Composite Quantum Systems
Nunzia Cerrato, Sauro Succi, Giacomo De Palma +1
Understanding how noise degrades entanglement is crucial for the development of reliable quantum technologies. While the Markovian approximation simplifies the analysis of noise, i…
Non-Clifford Cost of Random Unitaries
Lorenzo Leone, Salvatore F. E. Oliviero, Alioscia Hamma +2
Recent years have enjoyed a strong interest in exploring properties and applications of random quantum circuits. In this work, we explore the ensemble of -doped Clifford circuit…
The symplectic rank of non-Gaussian quantum states
Francesco Anna Mele, Salvatore Francesco Emanuele Oliviero, Varun Upreti +1
Non-Gaussianity is a key resource for achieving quantum advantages in bosonic platforms. Here, we investigate the symplectic rank: a novel non-Gaussianity monotone that satisfies r…
Multiparameter quantum estimation with Gaussian states: efficiently evaluating Holevo, RLD and SLD Cramér-Rao bounds
Shoukang Chang, Marco G. Genoni, Francesco Albarelli
Multiparameter quantum estimation theory is crucial for many applications involving infinite-dimensional Gaussian quantum systems, since they can describe many physical platforms,…
A tensor network approach to sensing quantum light-matter interactions
Aiman Khan, Francesco Albarelli, Animesh Datta
We present the fundamental limits to the precision of estimating parameters of a quantum matter system probed by light, even when some of the light is lost. This practically inevit…
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…
A complete theory of the Clifford commutant
Lennart Bittel, Jens Eisert, Lorenzo Leone +2
The Clifford group plays a central role in quantum information science. It is the building block for many error-correcting schemes and matches the first three moments of the Haar m…
Simultaneous optical phase and loss estimation revisited: measurement and probe incompatibility
Matheus Eiji Ohno Bezerra, Francesco Albarelli, Rafal Demkowicz-Dobrzanski
Quantum multiparameter metrology is hindered by incompatibility issues, such as finding a single probe state (probe incompatibility) and a single measurement (measurement incompati…
Exact non-Markovian master equations: a generalized derivation for Gaussian systems
Antonio D'Abbruzzo, Vittorio Giovannetti, Vasco Cavina
We derive an exact master equation that captures the dynamics of a quadratic quantum system linearly coupled to a Gaussian environment of the same statistics: the Gaussian Master E…
Formal Integration of Electron Scattering Processes via Separation of Dynamical and Geometric Contributions
Lorenzo Bagnasacco, Fabio Taddei, Vittorio Giovannetti
By decoupling the geometric from the dynamical contributions in the scattering processes, we develop a method to compute the scattering matrix of electrons in a one-dimensional coh…
Unifying quantum stochastic methods using Wick's theorem on the Keldysh contour
Vasco Cavina, Antonio D'Abbruzzo, Vittorio Giovannetti
We present a method, based on the Keldysh formalism, for deriving stochastic master equations that describe the non-Markovian dynamics of a quantum system coupled to a Gaussian env…
