Realization of quantum mechanical weak values of observables using entangled photons
G S Agarwal, P K Pathak
We present a scheme for realization of quantum mechanical weak values of observables using entangled photons produced in parametric down conversion. We consider the case when the s…
Quantum teleportation with pair-coherent states
Aurel Gabris, Girish S. Agarwal
Recently it has been argued that all presently performed continuous variable quantum teleportation experiments could be explained using a local hidden variable theory. In this pape…
Entanglement by linear SU(2) transformations: generation and evolution of quantum vortex states
G. S. Agarwal, J. Banerji
We consider the evolution of a two-mode system of bosons under the action of a Hamiltonian that generates linear SU(2) transformations. The Hamiltonian is generic in that it repres…
Quantum random walk of two photons in separable and entangled state
P. K. Pathak, G. S. Agarwal
We discuss quantum random walk of two photons using linear optical elements. We analyze the quantum random walk using photons in a variety of quantum states including entangled sta…
Two-bit Deutsch-Jozsa algorithm using an atomic ensemble
Shubhrangshu Dasgupta, G. S. Agarwal
The first optical proposal for the realization of the two-bit version of the Deutsch-Jozsa algorithm [D. Deutsch and R. Jozsa, Proc. R. Soc. London A {\bf 493}, 553 (1992)] is pres…
