Grover's search algorithm and the quantum measurement problem
Manoj K. Samal, Partha Ghose
It is suggested that the individual outcomes of a measurement process can be understood within standard quantum mechanics in terms of the measuring apparatus, treated as a quantum…
EPR Type Nonlocality in Classical Electrodynamics!
Partha Ghose, M. K. Samal
It is shown that classical electrodynamics in its alternative Kemmer-Duffin-Petiau-Harish-Chandra formulation surprisingly reveals a Hilbert space structure leading to the possibil…
Gravity Induced New Topological Phase in Optics
Partha Ghose, M. K. Samal
It is shown that both classical and quantum light can acquire a topological phase shift induced by classical gravity, and the latter is detectable in a laboratory-scale experiment.
Does nonorthogonality necessarily imply nonmaximal entanglement ?
Dipankar Home, M K Samal
We show that bipartite entanglements involving non-orthogonal states are {\it necessarily nonmaximally} entangled, however {\it small} the non-orthogonality may be. How the deviati…
