Quantum to classical transition and entanglement sudden death in Gaussian states under local heat bath dynamics
Sandeep K Goyal, Sibasish Ghosh
Entanglement sudden death in spatially separated two-mode Gaussian states coupled to local thermal and squeezed thermal baths is studied by mapping the problem to that of the quant…
Entanglement generation in spatially separated systems using quantum walk
C. M. Chandrashekar, Sandeep K. Goyal, Subhashish Banerjee
We present a novel scheme to generate entanglement between two spatially separated systems. The scheme makes use of spatial entanglement generated by a single-particle quantum walk…
Entanglement dynamics under local Lindblad evolution
Sandeep K. Goyal, Sibasish Ghosh
The phenomenon of entanglement sudden death (ESD) in finite dimensional composite open systems is described here for both bi-partite as well as multipartite cases, where individual…
