A new theoretical approach to the N-body quantum problem has been developed, providing, for the first time, a rigorous estimate of the errors made by approximate solutions calculated through numerical simulations using traditional methods. The N-body quantum problem,...
Due to their powerful information processing capabilities, artificial intelligence (AI) and, more broadly, neural network-based computing are generating increasing interest for their applications in the quantum domain. In two of our recent studies, we demonstrate how...
On July 3, 2024, Julien Laurat was honored with the prestigious Jean Jerphagnon Prize from the French Optical Society. An engineer graduated from the Ecole Supérieure d’Optique, Professor of Physics at Sorbonne University, and member of the Institut Universitaire de...
Researchers from the Kastler Brossel Laboratory (LKB) have created a system of cold dysprosium atoms whose spatial dynamics are correlated with their internal spin state. By interpreting these discrete internal degrees of freedom as fictitious lattice sites aligned...
Cold-atom elevator Published in Physical Review Letters, researchers from LKB and their colleagues have developed an ‘elevator’ for atoms, to connect quantum simulators to an atomic reservoir, paving the way for creating exotic quantum states and studying their...
