Inequivalence of Landau-Lifshitz and Landau-Lifshitz-Gilbert dynamics for a single quantum spin
Yuefei Liu, Olle Eriksson, Erik Sjöqvist
We examine the relation between the quantum Landau-Lifshitz equation (-LL) [Phys. Rev. Lett. 110, 147201 (2013)] and quantum Landau-Lifshitz-Gilbert equation (-LLG) [Phys. Re…
Subsystems (in)dependence in GIE proposals
Nicolas Boulle, Guilherme Franzmann
Recent proposals suggest that detecting entanglement between two spatially superposed masses would establish the quantum nature of gravity. However, these gravitationally induced e…
Breakdown of Non-Bloch Bulk-Boundary Correspondence and Emergent Topology in Floquet Non-Hermitian Systems
Hong Wu, Xue-Min Yang, Hui Liu
Topological edge states in gaps of non-Hermitian systems are robust due to topological protection. Using the non-Hermitian Floquet Su-Schrieffer-Heeger model, we show that this rob…
Structure of quantum measurements implementable with one round of classical communication
Arthur C. R. Dutra, Ties-A. Ohst, Hai-Chau Nguyen +1
Measurements that can be implemented via local operations and classical communication (LOCC) constitute a class of operations that is available in future quantum networks in which…
Universal computational super-resolution framework for imaging of quantum dots
Dominik Vašinka, Jaewon Lee, Charlie Stalker +9
We present a universal deep-learning method that reconstructs super-resolved images of quantum emitters from a single camera frame measurement. Trained on physics-based synthetic d…
Quantum signatures of proper time in optical ion clocks
Gabriel Sorci, Joshua Foo, Dietrich Leibfried +2
Optical clocks based on atoms and ions probe relativistic effects with unprecedented sensitivity by resolving time dilation due to atom motion or different positions in the gravita…
