Quantum Processes Which Do Not Use Coherence
Physical Review X, 2016 A major signature of quantum mechanics beyond classical physics is coherence, the existence of superposition states. The recently developed resource theory of quantum coherence allows the formalization of incoherent operations—those operations which ...

Coherence Analysis of Symmetric Star Topology Networks
Frontiers in Physics, 2022 The dynamics of complex networks are closely related to the topological structure. As an important research branch, the problem of network consensus has attracted more attention.

Amending coherence-breaking channels via unitary operations
, 2018 The coherence-breaking channels play a significant role in quantum information theory. We study the coherence-breaking channels and give a method to amend the coherence-breaking channels by applying unitary operations. For given incoherent channel $\Phi$,

, 2014 We introduce a rigorous framework for the quantification of coherence and identify intuitive and easily computable measures of coherence. We achieve this by adopting the viewpoint of coherence as a physical resource.

Theory of the Coherence of Topological Lasers
Physical Review X, 2020 We present a theoretical study of the temporal and spatial coherence properties of a topological laser device built by including saturable gain on the edge sites of a Harper-Hofstadter lattice for photons.

Axiomatic and operational connections between the $l_1$-norm of coherence and negativity
, 2018 Quantum coherence plays a central role in various research areas. The $l_1$-norm of coherence is one of the most important coherence measures that are easily computable, but it is not easy to find a simple interpretation.

Photoionization Suppression by Continuum Coherence: Experiment and Theory [PDF]
, 1999 We present experimental and theoretical results of a detailed study of laser-induced continuum structures (LICS) in the photoionization continuum of helium out of the metastable state 2s $^1S_0$.

Judgment and Decision Making, 2009 I show how the coherence/correspondence distinction can inform the conversation about decision methods for engineering design. Some engineers argue for the application of multi-attribute utility theory while others argue for what they call heuristics. To

Max- relative entropy of coherence: an operational coherence measure
, 2017 The operational characterization of quantum coherence is the corner stone in the development of resource theory of coherence. We introduce a new coherence quantifier based on max-relative entropy.

Measurement of angular distributions by use of low-coherence interferometry for light-scattering spectroscopy [PDF]
, 2001 We present a novel interferometer for measuring angular distributions of backscattered light. The new system exploits a low-coherence source in a modified Michelson interferometer to provide depth resolution, as in optical coherence tomography, but ...
