Research:

(a) An ingenious idea was formulated by invoking Quantum indistinguishability leading to an arbitrarily efficient resource for producing entanglement, applicable for spin-like variables of any two identical bosons/fermions (Phys. Rev. Lett. 88, 050401 (2002)). Entanglement being at the core of QI, this work stimulated applications of Quantum Statistics in QI processing, apart from being used in studies on free electron Quantum Computation.                


(b) A hitherto unexplored use of intraparticle path-spin entanglement (Physics Letters A 279, 281(2001) was conceived for empirically verifying Quantum Contextuality (subsequently tested, Nature 425, 45 (2003)), followed recently by suggesting its information-theoretic applications (Euro Physics Letters 89, 10005 (2010)). 


(c) The widely cited analysis of the Quantum Zeno effect (Annals of Physics 258, 237 (1997)), preceded by the formulation of a unified framework for such effects (Physics Letters A 173, 327 (1993)). 


(d) Proposed a novel experiment to demonstrate simultaneous wave and particle – like behaviour in the same setup using optical tunneling of single photon states (Physics Letters A 153, 403 (1991)), subsequently implemented (Physics Letters A 168, 1 (1992)). 


(e) Conceived an innovative biomolecular example to probe the Quantum Measurement Problem (Physical Review Letters 76, 2836 (1996)).
