BPS coherent states and localization
Journal of High Energy Physics, 2022 We introduce coherent states averaged over a gauge group action to study correlators of half BPS states in N $$ \mathcal{N} $$ = 4 SYM theory. The overlaps of these averaged coherent states are a generating function of correlators and can be written in ...

Journal of Physics A: Mathematical and Theoretical, 2012 The aim of this paper is to give a self-contained and unified presentation of a fermionic coherent state theory with the necessary mathematical details, discussing their definition, properties and some applications. After defining Grassmann algebras, it is possible to get a classical analog for the fermionic degrees of freedom in a quantum system ...

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.

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.

INTERFERENCE OF MULTI-MODE WEAK COHERENT STATES FOR TWIN-FIELD QUANTUM COMMUNICATION APPLICATIONS [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2019 Subject of Research. We present the results of analytical research and experimental implementation of quantum key distribution protocol based on multi-mode weak coherent states with untrusted detection node. Such states are based on interference of phase-

Circuit complexity for coherent states
Journal of High Energy Physics, 2018 We examine the circuit complexity of coherent states in a free scalar field theory, applying Nielsen’s geometric approach as in [1]. The complexity of the coherent states have the same UV divergences as the vacuum state complexity and so we consider the ...

Nonclassicalities of two-mode photon‑added coherent states
Results in PhysicsOne of the most promising nonclassical states in the context of quantum optics are hybrid coherent states, which include a combination of coherent states and single-photon-added coherent states.

Partial Recovery of Coherence Loss in Coherence-Assisted Transformation
Entropy, 2023 Coherence-assisted transformation under incoherent operations is discussed. For transformation from the pure state to the mixed state, we show that the coherence loss can be partially recovered by adding auxiliary coherent states.
