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…
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_…
