Study of atomic entanglement in multimode cavity optics
P. Saha, N. Nayak, A. S. Majumdar
The resonant interaction between two two-level atoms and m- electromagnetic modes in a cavity is considered. Entanglement dynamics between two atoms is examined. In particular we c…
Teleportation via maximally and non-maximally entangled mixed states
Satyabrata Adhikari, Archan S. Majumdar, Sovik Roy +2
We study the efficacy of two-qubit mixed entangled states as resources for quantum teleportation. We first consider two maximally entangled mixed states, viz., the Werner state\cit…
The Quadratic Spin Squeezing Operators
P. K. Pathak, R. N. Deb, N. Nayak +1
We discuss generic spin squeezing operators (quadratic in angular momentum operators) capable of squeezing out quantum mechanical noise from a system of two-level atoms (spins) in…
Teleportation of two-mode squeezed states
S. Adhikari, A. S. Majumdar, N. Nayak
We consider two-mode squeezed states which are parametrized by the squeezing parameter and the phase. We present a scheme for teleporting such entangled states of continuous variab…
Broadcasting of continuous variable entanglement
Satyabrata Adhikari, A. S. Majumdar, N. Nayak
We present a scheme for broadcasting of continuous variable entanglement. We show how an initial two-mode squeezed state of the electromagnetic field shared by two distant parties…
Control of atomic entanglement by dynamic Stark effect
Biplab Ghosh, A. S. Majumdar, N. Nayak
We study the entanglement properties of two three-level Rydberg atoms passing through a single-mode cavity. The interaction of an atom with the cavity field allows the atom to make…
