Efficient learning of ground & thermal states within phases of matter
Emilio Onorati, Cambyse Rouzé, Daniel Stilck França +1
We consider two related tasks: (a) estimating a parameterisation of a given Gibbs state and expectation values of Lipschitz observables on this state; and (b) learning the expectat…
Improving social welfare in non-cooperative games with different types of quantum resources
Alastair A. Abbott, Mehdi Mhalla, Pierre Pocreau
We investigate what quantum advantages can be obtained in multipartite non-cooperative games by studying how different types of quantum resources can lead to new Nash equilibria an…
A subpolynomial-time algorithm for the free energy of one-dimensional quantum systems in the thermodynamic limit
Hamza Fawzi, Omar Fawzi, Samuel O. Scalet
We introduce a classical algorithm to approximate the free energy of local, translation-invariant, one-dimensional quantum systems in the thermodynamic limit of infinite chain size…
A general quantum circuit framework for Extended Wigner's Friend Scenarios: logically and causally consistent reasoning without absolute measurement events
V. Vilasini, Mischa P. Woods
Extended Wigner's Friend Scenarios (EWFSs) model agents themselves as unitarily evolving quantum systems, going beyond the standard use of quantum theory where agents are treated c…
Quantum algorithm for ground state energy estimation using circuit depth with exponentially improved dependence on precision
Guoming Wang, Daniel Stilck França, Ruizhe Zhang +2
A milestone in the field of quantum computing will be solving problems in quantum chemistry and materials faster than state-of-the-art classical methods. The current understanding…
Monogamy of entanglement between cones
Guillaume Aubrun, Alexander Müller-Hermes, Martin Plávala
A separable quantum state shared between parties and can be symmetrically extended to a quantum state shared between party and parties for every $k\in…
A hierarchy of efficient bounds on quantum capacities exploiting symmetry
Omar Fawzi, Ala Shayeghi, Hoang Ta
Optimal rates for achieving an information processing task are often characterized in terms of regularized information measures. In many cases of quantum tasks, we do not know how…
Generalised entropy accumulation
Tony Metger, Omar Fawzi, David Sutter +1
Consider a sequential process in which each step outputs a system and updates a side information register . We prove that if this process satisfies a natural "non-signalli…
Learning quantum many-body systems from a few copies
Cambyse Rouzé, Daniel Stilck França
Estimating physical properties of quantum states from measurements is one of the most fundamental tasks in quantum science. In this work, we identify conditions on states under whi…
Receiver-Device-Independent Quantum Key Distribution
Marie Ioannou, Maria Ana Pereira, Davide Rusca +9
We present protocols for quantum key distribution in a prepare-and-measure setup with an asymmetric level of trust. While the device of the sender (Alice) is partially characterize…
A game of quantum advantage: linking verification and simulation
Daniel Stilck França, Raul Garcia-Patron
We present a formalism that captures the process of proving quantum superiority to skeptics as an interactive game between two agents, supervised by a referee. Bob, is sampling fro…
On contraction coefficients, partial orders and approximation of capacities for quantum channels
Christoph Hirche, Cambyse Rouzé, Daniel Stilck França
The data processing inequality is the most basic requirement for any meaningful measure of information. It essentially states that distinguishability measures between states decrea…
Autonomous Quantum Devices: When Are They Realizable without Additional Thermodynamic Costs?
Mischa P. Woods, Michał Horodecki
The resource theory of quantum thermodynamics has been a very successful theory and has generated much follow-up work in the community. It requires energy-preserving unitary operat…
