Transcoherent States: Optical States for Maximal Generation of Atomic Coherence
PRX Quantum, 2020 Quantum technologies are built on the power of coherent superposition. Atomic coherence is typically generated from optical coherence, most often via Rabi oscillations.

Geometric phases for nonlinear coherent and squeezed states [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2011 The geometric phases for standard coherent states which are widely used in quantum optics have attracted a large amount of attention. Nevertheless, few physicists consider about the counterparts of non-linear coherent states, which are useful in the description of the motion of a trapped ion.

Overcoming detection loss and noise in squeezing-based optical sensing
npj Quantum Information, 2021 Among the known resources of quantum metrology, one of the most practical and efficient is squeezing. Squeezed states of atoms and light improve the sensing of the phase, magnetic field, polarization, mechanical displacement. They promise to considerably

Optimized Squeezing Operation for Phase-Shift Keying Quantum State Discrimination
IEEE Access, 2022 Many receiver designs have been studied in the past to discriminate Phase-Shift Keying (PSK) quantum states that are used to encode information before transmitting over the communication channel.

Distillation of maximally correlated bosonic matter from many-body quantum coherence [PDF]
Quantum, 2020 We construct quantum coherence resource theories in symmetrized Fock space (QCRTF), thereby providing an information-theoretic framework that connects analyses of quantum coherence in discrete-variable (DV) and continuous variable (CV) bosonic systems ...

Deformed Coherent and Squeezed States of Multiparticle Processes
, 2003 Deformed squeezed states are introduced as the $q$-analogues of the conventional undeformed harmonic oscillator algebra squeezed states. It is shown that the boundary vectors in the matrix-product states approach to multiparticle diffusion processes are ...

Optimal squeezing for quantum target detection
Physical Review Research, 2021 It is not clear if the performance of a quantum lidar or radar, without an idler and only using Gaussian resources, could exceed the performance of a semiclassical setup based on coherent states and homodyne detection.

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