Reduction-based strategy for optimal control of Bose-Einstein condensates

J. Adriazola et al.

Summary: This article proposes a control strategy for the applications of Bose-Einstein condensates (BEC) based on optimal control methods. By using Galerkin expansion and a hybrid control strategy, excitations in the system can be greatly reduced.

Entanglement Hamiltonian tomography in quantum simulation

Christian Kokail et al.

Summary: The paper discusses an efficient tomographic protocol for studying entanglement structures in quantum many-body systems using few measurements. The protocol allows for the measurement of entanglement spectra in spin systems and has been demonstrated on trapped-ion quantum simulators. It addresses the challenge of measuring entanglement in quantum simulation and brings subsystems of tens of spins within reach for current experiments.

Observation of fragmentation of a spinor Bose-Einstein condensate

Bertrand Evrard et al.

Summary: In this study, a three-fragment condensate was produced for a mesoscopic spin-1 gas with anti-ferromagnetic interactions and vanishing collective spin. The reconstructed state was found to be close to the expected many-body ground state using spin-resolved detection, while one-body observables remained the same as for a completely mixed state. This highlights how the interplay between symmetry and interactions generates entanglement in a mesoscopic quantum system.

Quantum State Control of a Bose-Einstein Condensate in an Optical Lattice

N. Dupont et al.

Summary: This study presents an efficient design of quantum optimal-control protocols for manipulating the motional states of atomic Bose-Einstein condensate in a one-dimensional optical lattice. By varying the lattice position, a wide variety of targets can be reached, including single or multiple quantized momentum states with full control on the relative phase between different momentum components.
