Entanglement has widely researched nowadays worldwide because of its applications in the field of technology. A significant problem is its detection is dealt in this paper. Many methods for entanglement detection and problems associated them are given. An entanglement criterion based on probability amplitudes is derived and tricks which helps in finding a suitable entanglement witness for two qubit systems is explained.

Keywords: Entaglement, Probability amplitude, Two qubit system.
