Abstract: We present various results on the scheme introduced , which is a quantum spatial-search algorithm on a two-dimensional (2D) square spatial grid, realized with a 2D Dirac discrete-time quantum walk (DQW) coupled to a Coulomb […]
Continuer la lectureFrancesca Chittaro (LIS, Univ. Toulon): Introduction to Quantum control
Abstract: In this lecture, I will explain the aim and some results in QuantumControl (more precisely, control theory of quantum systems). I will also present some recent results on the control of bipartite open quantum systems. […]
Continuer la lectureConstantin Dalyan (LIP6/Pasqal) : Classically Approximating Variational Quantum Machine Learning with Random Fourier Feature
Abstract: Many applications of quantum computing in the near term rely on variational quantum circuits (VQCs). They have been showcased as a promising model for reaching a quantum advantage in machine learning with current noisy intermediate […]
Continuer la lectureFrancesca Chittaro (LIS, Univ. Toulon): Introduction to Quantum Mechanics
Abstract: In this lecture, I will explain the basic notions of the formalism of quantum mechanics. More precisely, I will present the postulates of quantum mechanics and we will discuss the following notions: state vector (and […]
Continuer la lectureJiaqi Leng (QuICS – University of Maryland): Quantum Simulation of Real-Space Dynamics
Abstract : We develop quantum algorithms for simulating the dynamics of interacting quantum particles in $d$ dimensions. Compared to the best previous results, our algorithm is exponentially better in terms of the discretization error \epsilon and polynomially […]
Continuer la lectureTitouan Carette (Latvia University): Perfect matchings, Quantum computing and ZW-calculus
Abstract : In 2002, Valiant introduced matchgates, a computational model based on perfect matching in graphs. Independently, in 2010, Coecke and Kissinger developed the ZW-calculus, a graphical language inspired by two families of multipartite states, the […]
Continuer la lectureAlexis Toumi (LIS, CaNa): Category Theory for Quantum Natural Language Processing
Abstract : Quantum natural language processing (QNLP) is the use of quantum computing to solve NLP tasks faster than any classical computer. In my PhD, I used category theory to implement QNLP models as homomorphisms from […]
Continuer la lectureMohamed Sabri (Tohoku University): An electric circuit induced by quantum walks
Abstract : In this talk, I will introduce the tailed model of quantum walks and some of its interesting results. Quantum walk is the quantum analogy of random walk. Unlike the usual quantum walks, the tailed […]
Continuer la lectureRavi Kunjwal (ULB, QuIC), Contextuality in composite systems: entanglement vs the Kochen-Specker theorem
Abstract: The Kochen-Specker (KS) theorem is often taken as a notion of nonclassicality that is independent of entanglement since it is provable on a three-dimensional Hilbert space. However, the smallest system on which both the KS theorem and entanglement […]
