TITLE: Effects of Amplification on Macroscopic Entangled States
ABSTRACT: Quantum information is a rapidly growing field with several important practical applications. It is highly desirable to construct and implement devices that utilize quantum information. Most classical encryption can be broken easily with a quantum computer using Shor's Algorithm. Also, with quantum communication and quantum key distribution one can send absolutely secure communications. One topic that is paramount in the field of quantum information is that of entanglement. In this work we propose to analyze the intricacies of amplifying entangled coherent states or Schrödinger cat states for the use of macroscopic quantum information. We do this using a quasi-probabilistic perspective. As it stands, we find that amplifying entangled states is more detrimental to entanglement than one might expect. We thus propose to further examine this problem.
