Identical-Particle Symmetry-Enabled Complete Coherent Control of Ultracold Atomic and Molecular Collisions
Jing-Chen Zhang, Adrien Devolder, Timur V. Tscherbul +2
We show that exchange symmetry in collisions of identical particles enables symmetry-protected coherent control of the total scattering cross section. For identical fermions, antis…
General framework for quantifying entanglement production in ultracold molecular collisions and chemical reactions
Adrien Devolder, Paul Brumer, Timur Tscherbul
Entanglement, a defining feature of quantum mechanics, arises naturally from interactions between molecular systems. Yet the precise nature and quantification of entanglement in th…
Leveraging Reactant Entanglement in the Coherent Control of Ultracold Bimolecular Chemical Reactions
Adrien Devolder, Timur Tscherbul, Paul Brumer
Entanglement is a crucial resource for achieving quantum advantages in quantum computation, quantum sensing, and quantum communication. As shown in this Letter, entanglement is als…
Time-Reversal Symmetry-Protected Coherent Control of Ultracold Molecular Collisions
Adrien Devolder, Timur V. Tscherbul, Paul Brumer
Coherent control of atomic and molecular scattering relies on the preparation of colliding particles in superpositions of internal states, establishing interfering pathways that ca…
