Number state filtered coherent states
Quantum Information Processing, 2018 Number state filtering in coherent states leads to sub-Poissonian photon statistics. These states are more suitable for phase estimation when compared with the coherent states. Nonclassicality of these states is quantified in terms of the negativity of the Wigner function and the entanglement potential.

Sequential state discrimination of coherent states. [PDF]
Sci Rep, 2018 AbstractSequential state discrimination is a strategy for quantum state discrimination of a sender’s quantum states when N receivers are separately located. In this report, we propose optical designs that can perform sequential state discrimination of two coherent states.

Coherent States for Tremblay-Turbiner-Winternitz Potential [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2012 In this study, we construct the coherent states for a particle in the Tremblay-Turbiner-Winternitz potential by finding the conserved charge coherent states of the four harmonic oscillators in the polar coordinates.

Experimental quantum secret sharing based on phase encoding of coherent states [PDF]
Science China Physics Mechanics and Astronomy, 2023 Quantum secret sharing (QSS) is one of the basic communication primitives in future quantum networks which addresses part of the basic cryptographic tasks of multiparty communication and computation. Nevertheless, it is a challenge to provide a practical

High Photon Number Entangled States and Coherent State Superposition from the Extreme Ultraviolet to the Far Infrared. [PDF]
Physical Review Letters, 2021 We present a theoretical demonstration on the generation of entangled coherent states and of coherent state superpositions, with photon numbers and frequencies orders of magnitude higher than those provided by the current technology.

Single-shot discrimination of coherent states beyond the standard quantum limit [PDF]
, 2021 The discrimination of coherent states is a key task in optical communication and quantum key distribution protocols. In this work, we use a photon-number-resolving detector, the transition-edge sensor, to discriminate binary-phase-shifted coherent states

Coherent state excitations and string-added coherent states in gauge-gravity correspondence
Nuclear Physics B, 2023 We analyze detailed properties of BPS coherent states and their connection to gravity. We interpret the group integral coherent state as a path integral over auxiliary variables coupled to the elementary letters of the theory. The eigenvalues of coherent
