The author is supported by a Senior Research Fellowship (SRF) from the Council of Scientific and Industrial Research (CSIR), Govt. of India. It is my pleasure to thank Aalok Misra, who motivated me to work on the entanglement stuff, and for his blessings. We would also like to thank Juan Maldacena, Andreas Karch, Kostas Skenderis and Tadashi Takayanagi for very helpful discussions and comments. This research was also supported in part by the International Centre for Theoretical Sciences (ICTS) for the program “Nonperturbative and Numerical Approaches to Quantum Gravity, String Theory and Holography” (code:ICTS/numstrings-2022/8). Various conferences/workshops; e.g., Mysteries of Universe-I (Institute Lecture Series) and Indian Strings Meeting 2021 at Indian Institute of Technology Roorkee, Roorkee, India; Applications of Quantum Information in QFT and Cosmology at the University of Lethbridge, Canada; Kavli Asian Winter School (KAWS) on Strings, Particles and Cosmology (Online) at International Centre for Theoretical Sciences (ICTS) Bangalore, India (code:ICTS/kaws2022/1); Reconstructing the Gravitational Hologram with Quantum Information at Galileo Galilei Institute for Theoretical Physics, Florence, Italy; Quantum Information in QFT and AdS/CFT-III at Indian Institute of Technology Hyderabad, India; helped me to learn about the information paradox and related stuff. I am very thankful to the speakers and organizers of these conferences because I learned about the subject from these conferences.
