Quantum sealed-bid auction using a modified scheme for multiparty circular quantum key agreement
Rishi Dutt Sharma, Kishore Thapliyal, Anirban Pathak
A feasible, secure and collusion-attack-free quantum sealed-bid auction protocol is proposed using a modified scheme for multi-party circular quantum key agreement. In the proposed…
Teleportation of a qubit using entangled non-orthogonal states: A comparative study
Mitali Sisodia, Vikram Verma, Kishore Thapliyal +1
The effect of non-orthogonality of an entangled non-orthogonal state based quantum channel is investigated in detail in the context of the teleportation of a qubit. Specifically, a…
A Comment on the One Step Quantum Key Distribution Based on EPR Entanglement
Anirban Pathak, Kishore Thapliyal
Recently, in Sci. Rep. \textbf{6} (2016) 28767, Li et al., have proposed a scheme for quantum key distribution using Bell states. This comment provides a proof that the proposed sc…
Quantum cryptography over non-Markovian channels
Kishore Thapliyal, Anirban Pathak, Subhashish Banerjee
A set of schemes for secure quantum communication are analyzed under the influence of non-Markovian channels. By comparing with the corresponding Markovian cases, it is seen that t…
Orthogonal-state-based and semi-quantum protocols for quantum private comparison in noisy environment
Kishore Thapliyal, Rishi Dutt Sharma, Anirban Pathak
Private comparison is a primitive for many cryptographic tasks, and recently several schemes for the quantum private comparison (QPC) have been proposed, where two users can compar…
Asymmetric Quantum Dialogue in Noisy Environment
Anindita Banerjee, Chitra Shukla, Kishore Thapliyal +2
A notion of asymmetric quantum dialogue (AQD) is introduced. Conventional protocols of quantum dialogue are essentially symmetric as both the users (Alice and Bob) can encode the s…
Hierarchical Joint Remote State Preparation in Noisy Environment
Chitra Shukla, Kishore Thapliyal, Anirban Pathak
A novel scheme for quantum communication having substantial applications in practical life is designed and analyzed. Specifically, we have proposed a hierarchical counterpart of th…
A comparative study of protocols for secure quantum communication under noisy environment: single-qubit-based protocols versus entangled-state-based protocols
Vishal Sharma, Kishore Thapliyal, Anirban Pathak +1
The effect of noise on various protocols of secure quantum communication has been studied. Specifically, we have investigated the effect of amplitude damping, phase damping, squeez…
Analysis and improvement of Tian-Zhang-Li voting protocol based on controlled quantum teleportation
Kishore Thapliyal, Rishi Dutt Sharma, Anirban Pathak
Recently Tian, Zhang and Li (TZL) have proposed a protocol for voting based on controlled quantum teleportation (Int. J. Theor. Phys. DOI 10.1007/s10773-015-2868-8). We have critic…
