Quantum advantage from energy measurements of many-body quantum systems
Leonardo Novo, Juani Bermejo-Vega, Raúl García-Patrón
The problem of sampling outputs of quantum circuits has been proposed as a candidate for demonstrating a quantum computational advantage (sometimes referred to as quantum "supremac…
Universal Limitations on Quantum Key Distribution over a Network
Siddhartha Das, Stefan Bäuml, Marek Winczewski +1
We consider the distribution of secret keys, both in a bipartite and a multipartite (conference) setting, via a quantum network and establish a framework to obtain bounds on the ac…
The Characterization of Noncontextuality in the Framework of Generalized Probabilistic Theories
David Schmid, John Selby, Elie Wolfe +2
To make precise the sense in which the operational predictions of quantum theory conflict with a classical worldview, it is necessary to articulate a notion of classicality within…
Generalized probability rules from a timeless formulation of Wigner's friend scenarios
Veronika Baumann, Flavio Del Santo, Alexander R. H. Smith +3
The quantum measurement problem can be regarded as the tension between the two alternative dynamics prescribed by quantum mechanics: the unitary evolution of the wave function and…
Quantum clocks and the temporal localisability of events in the presence of gravitating quantum systems
Esteban Castro-Ruiz, Flaminia Giacomini, Alessio Belenchia +1
The standard formulation of quantum theory relies on a fixed space-time metric determining the localisation and causal order of events. In general relativity, the metric is influen…
Multi-copy uncertainty observable inducing a symplectic-invariant uncertainty relation in position and momentum phase space
Anaelle Hertz, Ognyan Oreshkov, Nicolas J. Cerf
We define an uncertainty observable, acting on several replicas of a continuous-variable bosonic state, whose trivial uncertainty lower bound induces nontrivial phase-space uncerta…
Optimal estimation of parameters encoded in coherent states quadratures
M. Arnhem, E. Karpov, N. J. Cerf
In the context of multiparameter quantum estimation theory, we investigate the construction of linear schemes in order to infer two classical parameters that are encoded in the qua…
Classically simulating near-term partially-distinguishable and lossy boson sampling
Alexandra E. Moylett, Raúl García-Patrón, Jelmer J. Renema +1
Boson Sampling is the problem of sampling from the same distribution as indistinguishable single photons at the output of a linear optical interferometer. It is an example of a non…
Constraints on nonlocality in networks from no-signaling and independence
Nicolas Gisin, Jean-Daniel Bancal, Yu Cai +5
Generalising the concept of Bell nonlocality to networks leads to novel forms of correlations, the characterization of which is however challenging. Here we investigate constraints…
Regimes of classical simulability for noisy Gaussian boson sampling
Haoyu Qi, Daniel J. Brod, Nicolás Quesada +1
As a promising candidate for exhibiting quantum computational supremacy, Gaussian Boson Sampling (GBS) is designed to exploit the ease of experimental preparation of Gaussian state…
Quantum thermodynamics in a multipartite setting: A resource theory of local Gaussian work extraction for multimode bosonic systems
Uttam Singh, Michael G. Jabbour, Zacharie Van Herstraeten +1
Quantum thermodynamics can be cast as a resource theory by considering free access to a heat bath, thereby viewing the Gibbs state at a fixed temperature as a free state and hence…
Practical self-testing quantum random number generator based on an energy bound
Davide Rusca, Thomas van Himbeeck, Anthony Martin +5
We present a scheme for a self-testing quantum random number generator. Compared to the fully device-independent model, our scheme requires an extra natural assumption, namely that…
Analog quantum algorithms for the mixing of Markov chains
Shantanav Chakraborty, Kyle Luh, Jérémie Roland
The problem of sampling from the stationary distribution of a Markov chain finds widespread applications in a variety of fields. The time required for a Markov chain to converge to…
Quantum rebound capacity
Siddhartha Das, Mark M. Wilde
Inspired by the power of abstraction in information theory, we consider quantum rebound protocols as a way of providing a unifying perspective to deal with several information-proc…
Quantifying Bell: the Resource Theory of Nonclassicality of Common-Cause Boxes
Elie Wolfe, David Schmid, Ana Belén Sainz +2
We take a resource-theoretic approach to the problem of quantifying nonclassicality in Bell scenarios. The resources are conceptualized as probabilistic processes from the setting…
Maximal randomness from partially entangled states
Erik Woodhead, Jędrzej Kaniewski, Boris Bourdoncle +4
We investigate how much randomness can be extracted from a generic partially entangled pure state of two qubits in a device-independent setting, where a Bell test is used to certif…
