Capacity of coherent-state adaptive decoders with interferometry and single-mode detectors [PDF]
, 2017 A class of Adaptive Decoders (AD's) for coherent-state sequences is studied, including in particular the most common technology for optical-signal processing, e.g., interferometers, coherent displacements and photon-counting detectors.

Parallel single-shot measurement and coherent control of solid-state spins below the diffraction limit [PDF]
Science, 2020 Addressing the many and the individual The ability to coherently manipulate the quantum state of atomic defects in solid-state systems is a promising route to developing a platform for quantum technologies.

NeuralRecon: Real-Time Coherent 3D Reconstruction from Monocular Video [PDF]
Computer Vision and Pattern Recognition, 2021 We present a novel framework named NeuralRecon for real-time 3D scene reconstruction from a monocular video. Unlike previous methods that estimate single-view depth maps separately on each key-frame and fuse them later, we propose to directly reconstruct

Vector coherent state representations, induced representations, and geometric quantization: II. Vector coherent state representations [PDF]
, 2002 It is shown here and in the preceeding paper (quant-ph/0201129) that vector coherent state theory, the theory of induced representations, and geometric quantization provide alternative but equivalent quantizations of an algebraic model. The relationships

Coherent State Quantization of Constraint Systems [PDF]
, 1996 A careful reexamination of the quantization of systems with first- and second-class constraints from the point of view of coherent-state phase-space path integration reveals several significant distinctions from more conventional treatments.

Optical Synthesis of Large-Amplitude Squeezed Coherent-State Superpositions with Minimal Resources. [PDF]
Physical Review Letters, 2015 We propose and experimentally realize a novel versatile protocol that allows the quantum state engineering of heralded optical coherent-state superpositions. This scheme relies on a two-mode squeezed state, linear mixing, and a n-photon detection.

SU(2) symmetry of coherent photons and application to Poincaré rotator
Frontiers in Physics, 2023 Lie algebra is a hidden mathematical structure behind various quantum systems realised in nature. Here, we consider SU(2) wavefunctions for polarisation states of coherent photons emitted from a laser source, and discuss the relationship to spin ...

Coherent States for the Hydrogen Atom [PDF]
, 1995 The long-standing problem of finding coherent states for the (bound state portion of the) hydrogen atom is positively resolved. The states in question: (i) are normalized and are parameterized continuously, (ii) admit a resolution of unity with a ...

Coherent-state path integral versus coarse-grained effective stochastic equation of motion: From reaction diffusion to stochastic sandpiles. [PDF]
Physical Review E, 2015 We derive and study two different formalisms used for nonequilibrium processes: the coherent-state path integral, and an effective, coarse-grained stochastic equation of motion.
