Dualism in Entanglement and Testing Quantum to Classical Transition of Identicity
S. Bose, D. Home
We show a hitherto unexplored consequence of the property of identicity in quantum mechanics. If two identical objects, distinguished by a dynamical variable A, are in certain enta…
Ipso-information-transfer
John V. Corbett, Dipankar Home
A tripartite system with entangled non-orthogonal states is used to transfer retrievable or usable information without requiring an external channel, ipso-information-transfer (IIT…
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…
Interpreting the time of decay measurement: phenomenological significance of the Bohm model
A. S. Majumdar, Dipankar Home
We point out that the spreading of wave packets could be significant in affecting the analysis of experiments involving the measurement of time of decay. In particular, we discuss…
Barrier Perturbation Induced Superarrivals and Nonlocality in a Time-Evolving Wave Packet
Somshubhro Bandyopadhyay, Dipankar Home
We compute the time evolving probability of a Gaussian wave packet to be reflected from a rectangular potential barrier which is perturbed by reducing its height. A time interval i…
Determination of When an Outcome is Actualised in a Quantum Measurement using DNA - Photolyase System
Dipankar Home, Rajagopal Chattopadhayaya
The biochemical attachment of photolyase to ultraviolet (uv) absorbed DNA molecules provides a method for registering whether a source has emitted photons. Here using laws of chemi…
