Relation between squeezing of vacuum fluctuations, quantum entanglement and sub-shot noise in Raman scattering
Anirban Pathak, Jaromir Krepelka, Jan Perina
A completely quantum description of Raman process is used to investigate the nonclassical properties of the modes in the stimulated, spontaneous and partially spontaneous Raman pro…
Two-step orthogonal-state-based protocol of quantum secure direct communication with the help of order-rearrangement technique
Preeti Yadav, R. Srikanth, Anirban Pathak
The Goldenberg-Vaidman (GV) protocol for quantum key distribution (QKD) uses orthogonal encoding states of a particle. Its security arises because operations accessible to Eve are…
Improved protocols of secure quantum communication using W states
Chitra Shukla, Anindita Banerjee, Anirban Pathak
Recently, Hwang et al. [Eur. Phys. J. D. 61, 785 (2011)] and Yuan et al. [Int. J. Theo. Phys. 50, 2403 (2011)] have proposed two efficient protocols of secure quantum communication…
On the group theoretic structure of a class of quantum dialogue protocols
Chitra Shukla, Vivek Kothari, Anindita Banerjee +1
Intrinsic symmetry of the existing protocols of quantum dialogue are explored. It is shown that if we have a set of mutually orthogonal -qubit states {\normalsize $\{|ϕ_{0}>,|ϕ_…
Efficient protocols for deterministic secure quantum communication using GHZ-like states
Anindita Banerjee, Anirban Pathak
Two protocols for deterministic secure quantum communication (DSQC) using GHZ-like states have been proposed. It is shown that one of these protocols can be modified to an equivale…
