Generalized Quantum Secret Sharing
Sudhir Kumar Singh, R. Srikanth
We explore a generalization of quantum secret sharing (QSS) in which classical shares play a complementary role to quantum shares, exploring further consequences of an idea first s…
Multi-partite Quantum Entanglement versus Randomization: Fair and Unbiased Leader Election in Networks
Sudebkumar Prasant Pal, Sudhir Kumar Singh, Somesh Kumar
In this paper we show that sufficient multi-partite quantum entanglement helps in fair and unbiased election of a leader in a distributed network of processors with only linear cla…
Computing sharp and scalable bounds on errors in approximate zeros of univariate polynomials
P. H. D. Ramakrishna, Sudebkumar Prasant Pal, Samir Bhalla +2
There are several numerical methods for computing approximate zeros of a given univariate polynomial. In this paper, we develop a simple and novel method for determining sharp uppe…
Unconditionally Secure Multipartite Quantum Key Distribution
Sudhir Kumar Singh, R. Srikanth
We consider the problem of secure key distribution among trustful agents: the goal is to distribute an identical random bit-string among the agents over a noisy channel suc…
Characterizing the combinatorics of distributed EPR pairs for multi-partite entanglement
Sudhir Kumar Singh, Somesh Kumar, Sudebkumar Prasant Pal
We develop protocols for preparing a GHZ state and, in general,a pure multi-partite maximally entangled state in a distributed network with apriori quantum entanglement between age…
