Résumé I tentatively explore in an informal way the concept of global expressivism and focus in particular on expressivism about meaning attributions and truth. I indicate that expressivists about meaning should not deny that there are meanings—they …

Résumé Recent literature has seen a quickening of interest in ways of domesticating illocutionary force in semantic terms. One line of thought takes inspiration from Chierchia and McConnell Ginet ( Meaning and Grammar , 2000) who influentially …

Résumé A dualism can be characterized as the exaggeration of a distinction, so that it is not intelligible anymore how the opposed entities can function together and play the roles they are naturally thought to have. Recently Peter Hanks and François …

Résumé Common forms of functionalism hold that one cannot have any types of propositional attitude without having a whole suite of them. Thus, one couldn’t (e.g.) have beliefs but not have desires, hopes, wishes, and the like. Accordingly, it is generally …

Résumé Many philosophers of language think that in using a declarative sentence "p" with its meaning in a language, one thereby performs the meaning-generated speech act of saying that p. The same goes for interrogative and imperative sentences and the …

Résumé This talk connects two questions that are seldom brought together: (1) whether propositional embedding requires a force/content distinction; and (2) what kind of compositional model applies to non-atomic propositions. It has three main goals. …

Résumé In this talk, I will explain the evolution of PCQT (formerly PCQC), the parisian hub for quantum technologies, in the context of the national "Plan …

Résumé Quantum communication networks enable applications ranging from highly secure communica-tion to clock synchronization and distributed quantum computing. Miniaturized, flexible, and cost-efficient resources will be key elements for ensuring the …

Résumé Quantum metrology is widely accepted as one of the most advanced pillars of quantum information, where quantum effects lead to enhanced precision measurements of unknown quantities. On the other hand, quantum cryptography uses quantum systems to …

Résumé In this talk I will present the research I carried out along the last few years as postdoc at the Centre de Nanosciences et de Nanotechnologies (C2N, Université Paris-Saclay). I will start introducing basic concepts of quantum optics, continuous …

Résumé Due to the special no-cloning principle, quantum states appear to be very useful in cryptography. But this very same property also has drawbacks: when receiving a quantum state, it is nearly impossible for the receiver to efficiently check …

Résumé Negativity of the Wigner function is arguably one of the most striking non-classical features of quantum states. Beyond its fundamental relevance, it is also a necessary resource for quantum speedup with continuous variables. As quantum …

Résumé In measurement-based quantum computing (MBQC), computation is carried out by a  sequence of measurements and corrections on an entangled state. Flow, and related concepts, are powerful techniques for characterising the dependence of the corrections …

Résumé In recent years, many quantum machine learning algorithms have been proposed that can potentially offer significant speedup over corresponding classical algorithms. In this talk, we will discuss what is needed for a full-scale, fault-tolerant, …

Résumé Inferring the underlying physical state of a system from measurement  results is a fundamental task in physics. Remarkably, quantum mechanics enables the strongest form of inference:  there exist states known to be fully characterized (up to local …

Résumé Quantum physics proved to have an edge for outstanding applications in computation and cryptography.  Whether quantum technologies can help us facing the forthcoming energetic crisis remains, however, an open question.  In this work, we analyze the …
