Dynamics of Quantum Coherence and Quantum Fisher Information of a V-type Atom in Isotropic Photonic Crystal
Ghafar Ahmadi, Shahpoor Saeidian, Ghasem Naeimi
The time evolution of quantum Fisher information, quantum coherence, and non-Markovianity of a V-type three-level atom embedded in free space or a photonic band gap crystal have be…

Phase estimation of definite photon number states by using quantum circuits
Peyman Najafi, Ghasem Naeimi, Shahpoor Saeidian
We propose a method to map the conventional optical interferometry setup into quantum circuits. The unknown phase shift inside a Mach-Zehnder interferometer in the presence of phot…

Phase-controlled Optical PT symmetry and asymmetric light diffraction in one- and two-dimensional optical lattices
Ali Akbar Naeimi, Elham Darabi, Ali Mortezapour +1
We propose a novel scheme for asymmetric light diffraction of a weak probe field into a one-dimensional (1D) and two-dimensional (2D) lattice occupied with cold atoms. The atoms ar…
