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…
Beyond the Goldenberg-Vaidman protocol: Secure and efficient quantum communication using arbitrary, orthogonal, multi-particle quantum states
Chitra Shukla, Anirban Pathak, R. Srikanth
It is shown that maximally efficient protocols for secure direct quantum communications can be constructed using any arbitrary orthogonal basis. This establishes that no set of qua…
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…
