Transparent reporting of research-related greenhouse gas emissions through the scientific COnduct initiative
Ryan Sweke, Paul Boes, Nelly H. Y. Ng +3
Estimating the greenhouse gas emissions of research-related activities is a critical first step towards the design of mitigation policies and actions. Here we propose and motivate…
Gravitationally induced decoherence vs space-time diffusion: testing the quantum nature of gravity
Jonathan Oppenheim, Carlo Sparaciari, Barbara Šoda +1
We consider two interacting systems when one is treated classically while the other system remains quantum. Consistent dynamics of this coupling has been shown to exist, and explor…
The two classes of hybrid classical-quantum dynamics
Jonathan Oppenheim, Carlo Sparaciari, Barbara Šoda +1
Coupling between quantum and classical systems is consistent, provided the evolution is linear in the state space, preserves the split of systems into quantum and classical degrees…
Catalytic Gaussian thermal operations
Benjamin Yadin, Hyejung H. Jee, Carlo Sparaciari +2
We examine the problem of state transformations in the framework of Gaussian thermal resource theory in the presence of catalysts. To this end, we introduce an expedient parametris…
Objective trajectories in hybrid classical-quantum dynamics
Jonathan Oppenheim, Carlo Sparaciari, Barbara Šoda +1
Consistent dynamics which couples classical and quantum degrees of freedom exists, provided it is stochastic. This dynamics is linear in the hybrid state, completely positive and t…
Resource distillation in convex Gaussian resource theories
Hyejung H. Jee, Carlo Sparaciari, Mario Berta
It is known that distillation in continuous variable resource theories is impossible when restricted to Gaussian states and operations. To overcome this limitation, we enlarge the…
Quasi-polynomial time algorithms for free quantum games in bounded dimension
Hyejung H. Jee, Carlo Sparaciari, Omar Fawzi +1
We give a converging semidefinite programming hierarchy of outer approximations for the set of quantum correlations of fixed dimension and derive analytical bounds on the convergen…
Bounding the resources for thermalizing many-body localized systems
Carlo Sparaciari, Marcel Goihl, Paul Boes +2
Understanding under which conditions physical systems thermalize is a long-standing question in many-body physics. While generic quantum systems thermalize, there are known instanc…
The first law of general quantum resource theories
Carlo Sparaciari, Lidia del Rio, Carlo Maria Scandolo +2
We extend the tools of quantum resource theories to scenarios in which multiple quantities (or resources) are present, and their interplay governs the evolution of physical systems…
Approximate Majorization
Michał Horodecki, Jonathan Oppenheim, Carlo Sparaciari
Although an input distribution may not majorize a target distribution, it may majorize a distribution which is close to the target. Here we introduce a notion of approximate majori…
Energetic instability of passive states in thermodynamics
Carlo Sparaciari, David Jennings, Jonathan Oppenheim
Passivity is a fundamental concept in thermodynamics that demands a quantum system's energy cannot be lowered by any reversible, unitary process acting on the system. In the limit…
A Resource Theory for Work and Heat
Carlo Sparaciari, Jonathan Oppenheim, Tobias Fritz
Several recent results on thermodynamics have been obtained using the tools of quantum information theory and resource theories. So far, the resource theories utilised to describe…
Gaussian state interferometry with passive and active elements
Carlo Sparaciari, Stefano Olivares, Matteo G. A. Paris
We address precision of optical interferometers fed by Gaussian states and involving passive and/or active elements, such as beam splitters, photodetectors and optical parametric a…
Probing qubit by qubit: properties of the POVM and the information/disturbance tradeoff
Carlo Sparaciari, Matteo G. A. Paris
We address the class of positive operator-valued measures (POVMs) for qubit systems that are obtained by coupling the signal qubit with a probe qubit and then performing a projecti…
Exact and approximate solutions for the quantum minimum-Kullback-entropy estimation problem
Carlo Sparaciari, Stefano Olivares, Francesco Ticozzi +1
The minimum Kullback entropy principle (mKE) is a useful tool to estimate quantum states and operations from incomplete data and prior information. In general, the solution of a mK…
The canonical Naimark extension for the Pauli quantum roulette wheel
Carlo Sparaciari, Matteo G. A. Paris
We address measurement schemes where certain observables are chosen at random within a set of non-degenerate isospectral observables and then measured on repeated preparations of a…
