Practical device-independent quantum cryptography via entropy accumulation
Device-independent cryptography goes beyond conventional quantum cryptography by
providing security that holds independently of the quality of the underlying physical devices …

Simple and tight device-independent security proofs
Device-independent security is the gold standard for quantum cryptography: not only is
security based entirely on the laws of quantum mechanics, but it holds irrespective of any a …

Optimality of independently randomized symmetric policies for exchangeable stochastic teams with infinitely many decision makers
We study stochastic teams (known also as decentralized stochastic control problems or
identical interest stochastic dynamic games) with large or countably infinite numbers of …

Inductive supervised quantum learning
In supervised learning, an inductive learning algorithm extracts general rules from observed
training instances, then the rules are applied to test instances. We show that this splitting of …

Mean-field limit of Bose systems: rigorous results
M Lewin - arxiv preprint arxiv:1510.04407, 2015 - arxiv.org
We review recent results about the derivation of the Gross-Pitaevskii equation and of the
Bogoliubov excitation spectrum, starting from many-body quantum mechanics. We focus on …

Axiomatic approach to contextuality and nonlocality
We present a unified axiomatic approach to contextuality and nonlocality based on the fact
that both are resource theories. In those theories, the main objects are consistent boxes …

Three-dimensionality of space and the quantum bit: an information-theoretic approach
It is sometimes pointed out as a curiosity that the state space of quantum two-level systems,
ie the qubit, and actual physical space are both three-dimensional and Euclidean. In this …
