Bosonic Gaussian channel and Gaussian witness entanglement criterion of continuous variables

Physical Review Research, 2023
We use quantum entanglement witnesses derived from Gaussian operators to study the separable criteria of continuous variable states. For bipartite system, we transform the validity of a Gaussian witness to a bosonic Gaussian channel problem.

Development of multi-channel high power rectangular RF window for LHCD system employing high temperature vacuum brazing technique

Journal of Physics: Conference Series, 2010
A 3.7 GHz., 120 kW (pulsed), lower hybrid current drive (LHCD) system is employed to drive non-inductive plasma current in ADITYA tokamak. The rf power is coupled to the plasma through grill antenna and is placed in vacuum environment. A vacuum break between the pressurized transmission line and the grill antenna is achieved with the help of a multi ...
