(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 (Physical Review Letters 88, 050401 (2002)). Entanglement being at the core of QI, this work has 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 by the Vienna group (Nature 425, 45 (2003)), followed recently by suggesting its information-theoretic applications (Euro Physics Letters 89, 10005 (2010)).
(c) A 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 show simultaneous wave and particle – like behaviour in the same setup using optical tunneling of single photon states (Physics Letters A 153, 403 (1991)), subsequently tested (Physics Letters A 168, 1 (1992)) at Hamamatsu Photonics laboratory, Japan.
(e) Conceived an innovative biomolecular example to probe the Quantum Measurement Problem (Physical Review Letters 76, 2836 (1996)), preceded by a demonstration of the quantum mechanical violation of classical realism for multiparticle systems even under strong macroscopic limiting conditions (Physical Review A 52, 4959 (1995)).

Physicist
A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles of which all ordinary matter is made to the behavior of the material Universe as a whole...

. He works on the fundamental aspects of quantum mechanics
Quantum mechanics
Quantum mechanics, also known as quantum physics or quantum theory, is a branch of physics providing a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. It departs from classical mechanics primarily at the atomic and subatomic...
, including quantum entanglement
Quantum entanglement
Quantum entanglement occurs when electrons, molecules even as large as "buckyballs", photons, etc., interact physically and then become separated; the type of interaction is such that each resulting member of a pair is properly described by the same quantum mechanical description , which is...
and Quantum communication
Quantum information science
Quantum information science is an area of study based on the idea that information science depends on quantum effects in physics. It includes theoretical issues in computational models as well as more experimental topics in quantum physics including what can and cannot be done with quantum...

Research
Dipanka's research interests are in the following areas:- Foundational issues of Quantum Mechanics like the Quantum Measurement Problem, Quantum Nonlocality, the Macroscopic limits of Validity of Quantum Mechanics, Time in Quantum Mechanics, and the Quantum Zeno effectQuantum Zeno effectThe quantum Zeno effect is a name coined by George Sudarshan and Baidyanath Misra of the University of Texas in 1977 in their analysis of the situation in which an unstable particle, if observed continuously, will never decay. One can nearly "freeze" the evolution of the system by measuring it...
. - Nonstandard interpretations (such the Bohmian model) and the possibility of empirically discriminating them from the standard interpretation.
- Connecting various foundations aspects of Quantum mechanics with realizable experiments using Neutron/Electron/Atomic interferometry and the Quantum Optical methods.
- Fundamental features of Quantum Entanglement, including aspects of Quantum Information Transfer/Processing such as Quantum Cryptography and Quantum Teleportation.
- Applications of Quantum Entanglement and Quantum Informations in the consmological scenario. Interplay between Black Hole Thermodynamics and Quantum Information.
Research Highlight
Dipankar Home is among the earliest Indian researchers initiating studies on Foundations of Quantum Mechanics that have gradually become linked with experiments, giving rise to the currently vibrant area of Quantum Information (QI). His manifold contributions include two distinctive Research-level Books: “Conceptual Foundations of Quantum Physics – An Overview from Modern Perspectives” (Plenum) and “Einstein’s Struggles with Quantum Theory: A Reappraisal” (Springer) with Forewords by Anthony Leggett and Roger Penrose respectively (Appendix A), while some of the significant works with his collaborators are:(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 (Physical Review Letters 88, 050401 (2002)). Entanglement being at the core of QI, this work has stimulated applications of Quantum Statistics in QI processing, apart from being used in studies on free electron Quantum Computation.
