Superdense Coding with Uniformly Accelerated Particle
Mehrnoosh Farahmand, Hosein Mohammadzadeh, Hossein Mehri-Dehnavi +1
We study superdense coding with uniformly accelerated particle in single mode approximation and beyond single mode approximation. We use four different functions, the capacity of s…
Quantum Thermodynamics and Quantum Entanglement Entropies in an Expanding Universe
Mehrnoosh Farahmand, Hosein Mohammadzadeh, Hossein Mehri-Dehnavi
We investigate an asymptotically spatially flat Robertson-Walker spacetime from two different perspectives. First, using von Neumann entropy, we evaluate the entanglement generatio…
Entanglement of arbitrary spin modes in an expanding universe
Zahra Ebadi, Hossein Mehri-Dehnavi, Behrouz Mirza +2
Pair particle creation is a well-known effect on the domain of field theory in curved space-time. It is shown that the entanglement generations for spin-0 and spin-1/2 modes are di…
Quantum teleportation with nonclassical correlated states in noninertial frames
Hossein Mehri-Dehnavi, Robabeh Rahimi, Hosein Mohammadzadeh +2
Quantum teleportation is studied in noninertial frame, for fermionic case, when Alice and Bob share a general nonclassical correlated state. In noninertial frames two fidelities of…
Pseudo-Entanglement Evaluated in Noninertial Frames
Hossein Mehri-Dehnavi, Behrouz Mirza, Hosein Mohammadzadeh +1
We study quantum discord, in addition to entanglement, of bipartite pseudo-entanglement in noninertial frames. It is shown that the entanglement degrades from its maximum value in…
Application of Pseudo-Hermitian Quantum Mechanics to a Complex Scattering Potential with Point Interactions
Hossein Mehri-Dehnavi, Ali Mostafazadeh, Ahmet Batal
We present a generalization of the perturbative construction of the metric operator for non-Hermitian Hamiltonians with more than one perturbation parameter. We use this method to…
