Optimal protocols for quantum metrology with noisy measurements
Sisi Zhou, Spyridon Michalakis, Tuvia Gefen
Measurement noise is a major source of noise in quantum metrology. Here, we explore preprocessing protocols that apply quantum controls to the quantum sensor state prior to the fin…
Area law for fixed points of rapidly mixing dissipative quantum systems
Fernando G. S. L. Brandao, Toby S. Cubitt, Angelo Lucia +2
We prove an area law with a logarithmic correction for the mutual information for fixed points of local dissipative quantum system satisfying a rapid mixing condition, under either…
Rapid mixing and stability of quantum dissipative systems
Angelo Lucia, Toby S. Cubitt, Spyridon Michalakis +1
The physics of many materials is modeled by quantum many-body systems with local interactions. If the model of the system is sensitive to noise from the environment, or small pertu…
Non-local propagation of correlations in long-range interacting quantum systems
Philip Richerme, Zhe-Xuan Gong, Aaron Lee +6
The maximum speed with which information can propagate in a quantum many-body system directly affects how quickly disparate parts of the system can become correlated and how diffic…
Persistence of locality in systems with power-law interactions
Zhe-Xuan Gong, Michael Foss-Feig, Spyridon Michalakis +1
Motivated by recent experiments with ultra-cold matter, we derive a new bound on the propagation of information in -dimensional lattice models exhibiting interactions wi…
Elementary excitations in gapped quantum spin systems
Jutho Haegeman, Spyridon Michalakis, Bruno Nachtergaele +3
For quantum lattice systems with local interactions, the Lieb-Robinson bound acts as an alternative for the strict causality of relativistic systems and allows to prove many intere…
