Maximum information states for coherent scattering measurements [PDF]
Nature Physics, 2020 The use of coherent light for precision measurements has been a key driving force for numerous research directions, ranging from biomedical optics1,2 to semiconductor manufacturing3. Recent work demonstrates that the precision of such measurements can be

Coherence concurrence for X states [PDF]
Quantum Information Processing, 2020 We study the properties of coherence concurrence and present a physical explanation analogous to the coherence of assistance. We give an optimal pure state decomposition which attains the coherence concurrence for qubit states. We prove the additivity of coherence concurrence under direct sum operations in another way. Using these results, we calculate

Coherent states on spheres [PDF]
Journal of Mathematical Physics, 2002 We describe a family of coherent states and an associated resolution of the identity for a quantum particle whose classical configuration space is the d-dimensional sphere Sd. The coherent states are labeled by points in the associated phase space T*(Sd).

Multipartite Spin Coherent States and Spinor States [PDF]
, 2023 Multipartite generalizations of spin coherent states are introduced and analyzed. These are the spin analogues of multimode optical coherent states as used in continuous variable quantum information, but generalized to possess full spin symmetry.

Entangled coherent states created by mixing squeezed vacuum and coherent light [PDF]
Optica, 2017 Entangled coherent states are shown to emerge, with high fidelity, when mixing coherent and squeezed vacuum states of light on a beam-splitter.

Security proof of continuous-variable quantum key distribution using three coherent states [PDF]
, 2017 We introduce a ternary quantum key distribution (QKD) protocol and asymptotic security proof based on three coherent states and homodyne detection. Previous work had considered the binary case of two coherent states and here we nontrivially extend this ...

Generalized Susskind–Glogower coherent states [PDF]
, 2021 International audienceSusskind-Glogower coherent states, whose Fock expansion coefficients include Bessel functions, have recently attracted considerable attention for their optical properties. Nevertheless, identity resolution is still an open question,

Geometry of spin coherent states [PDF]
, 2017 Spin states of maximal projection along some direction in space are called (spin) coherent, and are, in many respects, the ‘most classical’ available.
