Parametric Amplification of Continuous-Variable Entangled State for Loss-Tolerant Quantum Distributed Sensing [PDF]

open access: yesSensors
Quantum metrology exploits quantum states to achieve an estimation sensitivity beyond classical limits. In the continuous-variable (CV) regime, the squeezed state has been used to implement deterministic quantum sensing, but the quantum metrology ...

Implementation of Photonic Phase Gate and Squeezed States via a Two-Level Atom and Bimodal Cavity

open access: yesPhotonics, 2022
We propose a theoretical model for realizing a photonic two-qubit phase gate in cavity QED using a one-step process. The fidelity and probability of success of the conditional quantum phase gate is very high in the presence of cavity decay.

Helstrom Bound for Squeezed Coherent States in Binary Communication

open access: yesEntropy, 2022
In quantum information processing, using a receiver device to differentiate between two non-orthogonal states leads to a quantum error probability. The minimum possible error is known as the Helstrom bound. In this work, we study the conditions for state

Transactional Interpretation and the Generalized Poisson Distribution

open access: yesEntropy, 2022
The aim of this paper is to study the quantum-like approach to the description of the market in the context of the principle of minimum Fisher information. We wish to investigate the validity of using squeezed coherent states as market strategies.

Two-axis two-spin squeezed states

open access: yesPhysical Review Research, 2020
The states generated by the two-spin generalization of the two-axis countertwisting Hamiltonian are examined. We analyze the behavior at both short and long timescales, by calculating various quantities such as squeezing, spin expectation values ...
