Enhancement of vibrationally assisted energy transfer by proximity to exceptional points, probed by fluorescence-detected vibrational spectroscopy

Posted by dbos September 6, 2023Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Zeng-Zhao Li, K. Birgitta Whaley, , , | Summary: Emulation of energy transfer processes in natural systems on quantum platforms can further our understanding of complex dynamics in nature. One notable example is the demonstration of vibrationally assisted energy transfer (VAET) on a trapped-ion quantum emulator, which […]

A Control Architecture for Entanglement Generation Switches in Quantum Networks

Posted by dbos September 5, 2023Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Scarlett Gauthier, Gayane Vardoyan, Stephanie Wehner, , | Summary: Entanglement between quantum network nodes is often produced using intermediary devices – such as heralding stations – as a resource. When scaling quantum networks to many nodes, requiring a dedicated intermediary device for every pair of nodes introduces […]

Topological quantum synchronization of fractionalized spins

Posted by dbos September 5, 2023Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Christopher W. Wächtler, Joel E. Moore, , , | Summary: The gapped symmetric phase of the Affleck-Kennedy-Lieb-Tasaki (AKLT) model exhibits fractionalized spins at the ends of an open chain. We show that breaking SU(2) symmetry and applying a global spin-lowering dissipator achieves synchronization of these fractionalized […]

Gas clumping in the outskirts of galaxy clusters, an assessment of the sensitivity of STAR-X

Posted by dbos September 4, 2023MIT

Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Christian T. Norseth, Daniel R. Wik, John A. ZuHone, Eric D. Miller, Marshall W. Bautz | Summary: In the outskirts of galaxy clusters, entropy profiles measured from X-ray observations of the hot intracluster medium (ICM) drops off unexpectedly. One possible explanation for this effect is gas […]

Steering-induced phase transition in measurement-only quantum circuits

Posted by dbos September 4, 2023Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Dongheng Qian, Jing Wang, , , | Summary: Competing measurements alone can give rise to distinct phases characterized by entanglement entropy$unicode{x2013}$such as the volume law phase, symmetry-breaking (SB) phase, and symmetry-protected topological (SPT) phase$unicode{x2013}$that can only be discerned through quantum trajectories, making them challenging to observe experimentally.

Fermi Constraints on the Ejecta Speed and Prompt Emission Region of the Distant GRB 220101A

Posted by dbos September 4, 2023Stanford

Kavli Affiliate: Nicola Omodei | First 5 Authors: Lorenzo Scotton, Frédéric Piron, Nicola Omodei, Niccolò Di Lalla, Elisabetta Bissaldi | Summary: At redshift z = 4.618, GRB 220101A is the most distant gamma-ray burst (GRB) detected by Fermi/LAT to date. It is also a very energetic event, with an equivalent isotropic energy of $3.6times10^{54}$ erg. […]
