Non-destructive Orthonormal State Discrimination
M. Gupta, A. Pathak, R. Srikanth +1
We provide explicit quantum circuits for the non-destructive deterministic discrimination of Bell states in the Hilbert space , where is qudit dimension. We discuss…
Assisted Quantum Secret Sharing
Sudhir Kumar Singh, R. Srikanth
A restriction on quantum secret sharing (QSS) that comes from the no-cloning theorem is that any pair of authorized sets in an access structure should overlap. From the viewpoint o…
A combinatorial approach for studying LOCC transformations of multipartite states
Sudhir Kumar Singh, Sudebkumar Prasant Pal, Somesh Kumar +1
We develop graph theoretic methods for analysing maximally entangled pure states distributed between a number of different parties. We introduce a technique called {\it bicolored m…
Computable Functions, the Church-Turing Thesis and the Quantum Measurement Problem
R. Srikanth
It is possible in principle to construct quantum mechanical observables and unitary operators which, if implemented in physical systems as measurements and dynamical evolution, wou…
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…
A Computational Model for Quantum Measurement
R. Srikanth
Is the dynamical evolution of physical systems objectively a manifestation of information processing by the universe? We find that an affirmative answer has important consequences…
